I'm trying to figure how I can block all incoming and outgoing traffic except Teamviewer? I've been trying to achieve this with the Windows 7 firewall but with no success.

Anybody any ideas?

Within the Windows Firewall (basing myself from XP) disable all exceptions except Teamviewer. You could use another firewall... –  Doktoro Reichard Aug 24 '13 at 17:03
    
What have you tried? Ports 80? 443? 5938? –  Logman Aug 24 '13 at 17:33
    
Thanks for your respones. What iv'e tried so far is something i found on another forum. Deleting all inbound and outbound rules and created new inbound and outbound rules for teamviewer. –  Ray Aug 24 '13 at 17:58
    
I've tried something else. I blocked all the ports in my router to the computers ip adress except port 5938. Is this sufficient protection against possible virusses/trojans trying to " phone home"? –  Ray Aug 25 '13 at 9:25
    
never know for sure unless you disconnect it from the internet permanently. –  Logman Aug 25 '13 at 16:59

Which ports are used by TeamViewer? In general, TeamViewer will always work if surfing on the Internet is possible. Hence, no firewall configuration is required. As an alternative to port 80 HTTP, port 443 HTTPs is also being checked. In addition, it is also possible to open only port 5938 TCP on the outgoing side. Data traffic should then be able to pass through on this port without any problems.

If it worked you should try and write your own answer. –  Doktoro Reichard Aug 24 '13 at 21:23
