Disable TeamViewer from “stealing” Port 80?

Question

How can you disable TeamViewer from using/reserving port 80? I am certain in the previous version <v4.1.6 there used to be a radio button option in "options" which disabled it from needing it, but now I cannot find it.

Is port 80 serisouly required by this remote desktop app? It is conflicting with IIS on our development server and becoming a real pain.

Thanks all.

Answer 1

Did you enable the Direct-In Modus? You can disable it in

   Options > Advanced > Network > TeamViewer DirectIn check

From the manual, page 59 (PDF):

Check Opens a dialog where the availability of TeamViewer is checked. The DirectIn Ports 80 and 5938 do not have to be opened , however, TeamViewer can use these ports - if available - for establishing faster connections.

Answer 2

1. Open port 5938 (TCP) on your firewall.

2. Change the following registry keys.

   • [HKEY_LOCAL_MACHINE\SOFTWARE\ TeamViewer\Version4] Key ’GatewayAllowed’ set to 0 * [HKEY_LOCAL_MACHINE\SOFTWARE\TeamViewer\Version4] Key ’ListenHttp’ set to 0

Answer 3

If you are using Windows 7 x64, you will find that the registry keys are in a different location. I have searched the registry and cannot find anything along the lines of 'GatewayAllowed'. The other key is as follows:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TeamViewer\Version6\ListenHttp

Answer 4

Options > Advanced > Show Advanced Options > Don't use incoming ports 80 and 443

Answer 5

The DirectIn check merely checks whether port 80 is forwarded through your router, it does not stop hijacking port 80. There is a registry change that you can make (two values need to be changes, one obvious, one non). I don't have the details with me, but if you telephone TV tech support, ignore their "this is just how it works" and insist on talking to a tech, you may be able to get it. I'll post the changes as soon as I get to my own computer.

Answer 6

Starting the Apache server before teamviewer seems to solve this problem.

Answer 7

On the new teamviewer you go to advanced settings and then Don't use port 80

Answer 8

Please edit C:\Program Files\Apache Software Foundation\Apache2.2\conf\httpd.conf and look for the following lines:

#Listen 12.34.56.78:80
Listen 80

and change to, for instance:

#Listen 12.34.56.78:80
Listen 8080

Then, start Apache service (windows)

The above will cause apache to "listen" on port 8080.

Answer 9

i went to windows firewall and unchecked team viewer in exeptions (not team viwer remote..) and tried it.... it worked for me

Answer 10

You can delete the current rules in the firewall and then make new rules with different port numbers. I found this website that explains it in detail http://www.avg.com/au-en/51
