A stealth mobile redirect occurs when a site redirects a smartphone or tablet user to content that is not available to the crawler. A hidden redirect is considered a violation of the Google Webmaster Guidelines. The Google Search Quality Team may take action on sites with these redirects, such as de-indexing the URL.
Sometimes content has to be slightly adapted to the device on which the user is viewing it. For example, optimizing for a small smartphone screen involves changing images and other content elements. It will be more convenient for smartphone users to work not with the regular version of the site, but with the mobile one. Therefore, redirecting, for example, from example.com/url1 to m.example.com/url1 is justified. However, the hidden redirection of mobile users to other pages interferes with the work.
Violation example: The search results page on the computer and smartphone have the same URL. By clicking on this link, the computer user will be taken to the landing page, while the smartphone user will be redirected to another URL.
Site owners may intentionally set up stealth redirects for mobile users, but we are aware of instances where this occurs without the owners' knowledge. Here are the possible reasons:
- The code that creates the redirect rules.
- A script or element placed on a site to display ads or monetize content.
- A script or element placed by hackers that redirects to malicious sites.
How to detect hidden redirects
To detect hidden redirects on your site, follow these steps:
- Open the site on your smartphone and see if you get to another resource
We recommend that you check your site by going to it from the Google search results on your smartphone. When debugging, it is convenient to use emulation of mobile devices in computer browsers. You can, for example, check directly in Chrome, Firefox or Safari browsers. In the latter case, you will need to open the Safari preferences and check the "Show Develop menu in menu bar" checkbox.
- Read visitor reviews
Users may see your site differently than you. Always read customer reviews and pay attention to their complaints in order to identify problems in time.
- Track visitor actions and analyze site statistics
Unusual mobile user behavior can be detected by examining web analytics data. For example, if the average time spent on the site by mobile device owners (and only them) has dropped dramatically, this could be caused by a redirect.
Tracking changes in the activity of mobile users will help you identify hidden redirects in time. You can, which will warn of a sharp decrease in the number of visitors or the time they spend on the site. These factors do not necessarily mean that the site has hidden redirects, but they are still worth paying attention to.
How to remove hidden redirect
- Check if the site is hacked
- Check if there are any extraneous scripts and elements on the site
If your site is not hacked, check if there are any third-party scripts or elements on it that cause redirects. To do this, follow these steps:
- Remove third-party scripts and elements one by one from pages on which a redirect is detected.
- After each deletion, check from your mobile device or through the emulator if the redirect occurs.
- If you suspect that a certain script or element is performing a covert redirect, remove it from the site and ask its provider to help you debug it.
How to avoid hidden redirects in the future
Choose advertisers that won't direct your visitors to unexpected pages. If you're looking to build trust in the industry, check out our ad network best practices.

Cellular operators provide their subscribers with the potential to use a useful incoming call forwarding service, which, probably due to low user awareness, is used infrequently. In fact, call forwarding has a number of undeniable advantages, especially for owners of several numbers. When the battery is low on one phone, it is possible to quickly set call forwarding to a phone with a sufficient level of charge and even to a landline number. And with the help of operator support, you can quickly redirect calls even from a switched off phone.
Our review covers the call forwarding service provided by MegaFon as widely as possible and aims to enlighten and clarify both the nature of the service and the mechanism for setting it up.
Call forwarding on MegaFon
The essence of the Megafon call forwarding service is to transfer an incoming call from number 1 to number 2, which can be performed both unconditionally and following certain conditions. The following types of redirection can be distinguished:
- Forwarding on busy - if number 1 is busy, automatic forwarding to number 2 is performed. This option is indispensable for business people: not a single customer call will be lost. Instead of you, your partner can always answer the call.
- Forwarding on no answer - works only in situations when a working phone does not answer. The call is forwarded to the correct number. If the phone is turned off, then call forwarding will not be performed.
- Forwarding on unavailability - if your battery is dead or the call came while you were on the subway, the call of a client who cannot be lost will be forwarded to your colleague who is in the office with a charged phone.
- Forward Unconditional - All calls from phone 1, including when it is turned on and available to the network, are forwarded to phone 2.
The Megafon call forwarding service is available for installation on any number of a Russian operator, both mobile and landline. The exception is numbers starting with +7809 and +7803. It is not possible to forward already redirected calls, as well as to install the service on the number of a foreign operator. All forwarding numbers must be written in the international format (via +7).
It is possible to redirect calls to voice mail, for which you should register the number +79262000222 (Moscow region). If you live in another region, you can easily find the phone number to enable voice mail on the operator's website or by contacting the help desk. The Megaphone "Change dial tone" service does not work on calls forwarded to other numbers. Standard beeps are used.
When setting up the service, you do not need to pay either a subscription fee or a connection fee. Only the cost of a call to the number registered for forwarding is paid. Everything here is strictly individual and depends directly on the tariff you use. So, when forwarding to an MTS number, you will be charged for a call to MTS at the rates of your tariff.
Do not abuse call forwarding while abroad. The cost of unconditional call forwarding in roaming is the same as for calls in Russia, and in case of conditional call forwarding, double billing will be applied: both incoming and outgoing calls are charged.
Forwarding text messages on MegaFon
There is no possibility of forwarding SMS messages on MegaFon today. Some time ago there was an SMS+ service that allowed you to forward text messages, but it is no longer available.
How to connect MegaFon call forwarding?
The review quite fully highlights the advantages of the MegaFon call forwarding service, which may cause a natural desire among communication users to use it. There are the following ways to set call forwarding to your number:
- With the help of the operator's support service;
- By contacting the staff of any MegaFon communication salon;
- Having configured through phone parameters 4. Using USSD commands.
In the review, we will pay attention exclusively to the last two options. How to activate the service using methods No. 1 and No. 2 You can easily be prompted by friendly employees of the hotline.
So, method number 3 - use the settings of your phone. We find the call settings section in the menu, then the menu for setting call forwarding, where all possible options are indicated, you should choose the one that suits you, enter the number yourself, where incoming calls will be redirected. The phone will do the rest of the work itself and the cellular network will have access to the necessary settings.
USSD commands for connecting call forwarding Megafon
- **67*phone_number# - call forwarding on busy;
- **61*phone_number# - forwarding on no response (you can specify the response timeout, then the request will be like this:
- **61*phone_number*time# - time can be specified from 5 to 30 seconds, step 5 seconds);
- **62*phone_number# - call forwarding on unavailability;
- **21*phone_number# - unconditional forwarding.
It seems interesting to be able to combine conditional call forwarding types with each other (a new condition for each number), but when setting up an unconditional call forwarding type, all other conditional types are automatically disabled. The ability to set up a second line does not depend on the tariff plan and is always available, which is extremely convenient and allows you to control incoming calls.
How to disable MegaFon call forwarding?
The methods for disabling the MegaFon call forwarding service are similar to the methods indicated in the previous paragraph. Let's denote USSD requests:
- ##67# - cancellation of call forwarding on busy service; ##61# - refusal of call forwarding service due to no response;
- ##62# - cancellation of call forwarding service due to unavailability;
- ##21# - rejection of unconditional forwarding; ##002# - one-time rejection of redirection of any kind.
Additional commands
- *#phone_number 67# - checking the setting of call forwarding on busy;
- *#telephone_number 61# - checking the setting of call forwarding on no answer;
- *#telephone_number 62# - checking the call forwarding on unavailability;
- *#phone_number 21# - checking the setting of unconditional forwarding.
Answers to your requests will be entered on the mobile phone screen. Having seen them, you can easily disable those types of redirects that you no longer use or refuse the service entirely.
Mobile operators in 2019 offer customers a lot of additional services and options. Many of them turn out to be unclaimed, and the client simply does not suspect until a certain time that some of them are connected. This is the reason for frequent questions about how to remove this or that option. The same applies to finding information on how to turn off call forwarding on Megafon.
Many people ask the question, how to disable call forwarding on Megaphone? Before answering this question, it is worth explaining to users that such a service can be extremely useful, especially for active businessmen or entrepreneurs.
The option allows you to redirect a call that is made to a specific number to another subscriber or simply to another phone if the first one cannot accept the call for some reason.
Today, redirection from Megafon is divided into two types, conditional and unconditional, the first, in turn, has three more subsections. The user can make the desired combination of call forwarding settings in accordance with certain conditions. Or put an unconditional redirect by typing a combination **21*phone number#. It will not be possible to combine two types in one setting.
Types of conditional redirects:
- No answer to an incoming call. The call is redirected to the specified number if the user does not pick up the phone within the specified time period. The connection is made with a combination **61*<номер, на который будут перенаправляться звонки># . The standard unanswered call period is 30 seconds, the user can choose their own value from 5 to 30 seconds in 5-point intervals (10, 15, 20, and so on).
- If the phone is turned off or in an area with no network coverage, the call will be forwarded to another number assigned by the subscriber. To activate this setting, use the command **62*<номер переадресации> # and call button. If the user is unavailable, another person will answer the call.
- Call forwarding if the main subscriber is talking at the time of the call. This setting is convenient for organizing the work of an active manager or businessman, when it is important to receive and process each call so as not to miss a client. The call is redirected to any selected number. To connect, dial **67*<номер абонента, который примет звонок> # .
A minute of conversation during call forwarding is charged at a price of 2.5 rubles / minute within the home region and according to the terms of the tariff plan outside it. If the subscriber is outside the region in which the SIM card was issued. And redirection is connected inside, then its cost is calculated on normal terms.
In international roaming, the service is charged by adding the cost of incoming and outgoing calls from a particular country. Therefore, if you need to leave the country with a Megafon SIM card, turn off call forwarding in the first place.
Megafon: how to disable call forwarding
How to remove call forwarding on Megaphone? Before initiating a disconnection, the user should find out which service is connected to the number and then choose the appropriate combination. It is worth assessing the situation and deciding whether disconnection is really necessary, because in practice the service is very convenient and allows you not to miss a single call. It is especially convenient to use this service when changing the number, when all incoming calls from the old identifier are redirected to the new number.
Checking for connectivity
If the assessment of the situation showed that it still follows, then the first thing the client should do is find out the type of the connected option. The set of characters for checking is also different for each type, so we will consider them separately, we will also have to check in turn.
- To check if unconditional forwarding is active, dial *#21# .
- If it is necessary to check call forwarding under the condition of a long wait, when the subscriber does not pick up the phone, then *#61# .
- To clarify the presence of call forwarding due to unavailability of the subscriber - * # 62 #.
- To check call forwarding if the line is busy dial *#67# .
After the user dials each of the presented combinations, information will appear on the screen containing the status of the service and data on which number is redirected to under each of the conditions.
Shutdown
Having determined the redirection that is currently active, you can proceed to disable it. This also requires a certain combination, the character set of which depends on the specific type of service.
To disable redirects:
- if the redirect is unconditional, then dial ##21# ;
- to redirect if there is no answer, then ##61# ;
- if the call is redirected when there is no subscriber in the network ##62# ;
- the line is busy - ##67# .
This is not the only option to disable the service. In order to completely cancel all redirection of calls configured under certain conditions, dial the combination ##004# and the call key at the end. In this case, all conditional call forwarding will be cancelled. The character set is ##002# and the call will cancel any forwarding, regardless of its type.
To cancel any connected services, the client can contact the operator directly by calling the hotline. The support service will ask you to confirm the identity of the subscriber by indicating passport data and, possibly, the code word that was set at the time of registration of the SIM card.
After that, the representative of the mobile operator will disable all active call forwarding and relieve the client of the need to independently look for a solution to the problem.
Call forwarding service is connected and disconnected free of charge. Therefore, the client can manage the settings, knowing the combinations described above, and optimize communication costs in case of business trips or travel.
By activating the service, the subscriber can receive calls received, for example, on his work phone, from a smartphone or home phone. The option is provided by all mobile operators, including MTS.
Service description
Call forwarding is the ability of a mobile network to redirect an incoming call from one phone to another. The essence of the service is quite simple: when making a call to a certain phone number, the call is automatically redirected to a pre-designated other phone number. In this case, any number in the world can serve as the addressee.
Initially, this option was more used by business people even before the advent of Samsung Duos phones, capable of receiving calls simultaneously on two cards from one or two mobile operators. In this case, the subscriber could be reached under any circumstances only if the call forwarding service was activated.
You can configure the option through the menu in the Call Settings section. From the proposed list, you must select the appropriate type of redirection and save the changes. If necessary, the subscriber can select not one, but several numbers at once for call forwarding.
Types of forwarding
MTS provides several options for call forwarding, the choice of which is determined by the needs of the subscriber:
- Forwarding on unavailability - calls are redirected to another number if the first one is currently outside the coverage area of the mobile network;
- Call forwarding on busy - calls are forwarded if the phone number is busy at the time of the call;
- Forwarding on no answer - the call is redirected if the waiting limit on the line is exceeded;
- Forward Unconditional - Automatic forwarding of all calls to one or more numbers.
If at least one of the conditions is triggered, the call is automatically redirected to the number that was specified by the subscriber for forwarding. Any numbers can be selected as the second phone, as well as voice mail. It should be noted that activating the service in roaming will lead to an increase in the tariffication of calls by 2 times - both for outgoing and incoming calls at the same time.
How to connect?
There are several ways to enable call forwarding. The easiest way to do this is through the ussd command. The combination of numbers and characters directly depends on the type of forwarding that needs to be activated:
- Unconditional - **21*phone number#;
- For unavailability - **62*phone number#;
- For the lack of an answer - **61*phone number*waiting limit#;
- By employment - **67*phone number#.
You can find out information about how to connect the option when you call the help desk. However, this service is paid and is 30 rubles.
Connecting through the MTS website
Unregistered MTS subscribers can go through a quick registration and activate call forwarding through changes in the settings in the "Personal Account". To activate the option, you need to follow the following algorithm of actions:
- Log in to the website of the mobile operator mts.ru;
- On the left side of the screen, select the “Settings” category from the menu;
- Click on the "Call Forwarding" section;
- In the "Conditions" sub-item, select the appropriate type of forwarding (if you select the "forwarding on busy" item, specify the waiting time limit during a call);
- In the corresponding column, indicate the phone number to which incoming calls will be redirected;
- Finally, click on the "Apply" button to save the changes.
Before the phone number for forwarding, you must specify the country code "+7". Please note that you cannot forward already forwarded calls.
How to disable?
There are several ways to disable the option. As with connecting, the easiest way to make a system request is with the following combinations:
- Unconditional forwarding - ##21# ;
- Forwarding on busy - ##67# ;
- Forwarding on no answer - ##61# ;
- Forwarding on unavailability - ##62# .
After dialing the appropriate combination, press the call button. To deactivate any of the above redirects, you can use the universal ussd command - ##002# .
Shutdown via the Internet
You can deactivate the service on the mobile operator's website in the "Call Forwarding" section. To do this, just uncheck the box next to the selected forwarding method and click the "apply" button.
If the subscriber is a confident user of a mobile device, he can disable call forwarding through the My MTS application. In it, you need to find the "Call settings" item and deactivate the service.
Help mobile operator
You can opt out of call forwarding over the phone. To do this, call 8-800-250-0890 and ask the operator to disconnect you from the service. To convince you that call forwarding is deactivated, you can call 555 and use the voice menu to check the status of the option.

I just set up a DNS server for my own network and many guides on the internet suggest making sure that port forwarding to port 53 is not enabled.
What's not clear to me is: should this be configured at the router level or at the firewall level? If I do this on a firewall, how do I do this on an Ubuntu 12.04 server?
I have multiple clients on my home network, an ESXi server, and a home router. One of the VMs inside ESXi is a DNS server (running on an Ubuntu 12.04 server) that is used to handle local DNS requests, but is also configured to forward requests for external IP addresses to Google's DNS servers.

This will help ensure the topology of your network. Is your DNS server behind a router? Is your internal network on a private subnet or public? Is the router another server, a ready made home router, or an enterprise class router like Cisco? Is the DNS server supposed to handle requests from outside the network, or only inside? What OS is running on the DNS server? - Patrick 21 Apr. 14 2014-04-21 12:09:16

This must be configured on whatever hardware you have between the DNS server and the outside world. Port forwarding is AFAIK off by default on pretty much everything, so you shouldn't worry too much about it. If you are using residential network equipment, there should be port forwarding configuration options in the web interface. To check port forwarding settings on Ubuntu use IPTables:
$sudo iptables -t nat -vnL
To ultimately test your network for port forwarding use Netcat to connect to a port through your public IP:
$ nc -vu 53
You will have connections monitored on the DNS server to monitor the netcat connection as netcat may erroneously report that the connection was successful due to UDP incompatibility
