I'm not familiar with Teamviewer at all, but if it uses ports other than 80 and/or 443 you can simply block that traffic (or not allow it in the first place and let the default deny rule drop it).  If it uses port 80 you will need to use a protocol analyzer (e.g. Network Monitor or Wireshark) and observe the traffic for something unique to the communication that you can filter on (most often this is the user-agent request header).  If it uses port 443 you will need to employ a third-party filter to perform forward SSL inspection (on ISA, TMG will include this by default).

We have blocked this here:

- signature containing 'DynGate' (HTTP Header, User-Agent)
- url containing 'dyngate' (just to make sure ...)
- domain Teamviewer.com (to prevent acces to the Web access method at login.teamviewer.com)

Hope this help.

I'm in the same boat.  But mine situation is to allow a one way connection.  I want my folks to be able to control the customer's PC to assist the customer in fixing their problem. 

Teamviewer, in my opinion, is a good/light application to use.  But not being able to control the traffic is a problem for us.

I've try all I could find on the net. This is what I have done:

I've made address range from -

and New rule where I've denied access  from all networks to this address range, and it works OK. I'm not getting ID and PASS when I open Teamviewer!

If someone have better idea, I'm open for conversation.

hi do not speak English, I solved it as follows:
in the navigation rule with a exceptions add a url set:
http:// *. dyngate.com / *
http:// *. teamviewer.com / *
so far has worked.
