I believe that TeamViewer is a VNC derivative. Try blocking 5900

Which ports does TeamViewer use?
By default TeamViewer uses only the outgoing port 80 (HTTP) - no firewall configuration is necessary. Alternatively you can open port 5938 (TCP) for outgoing connections.
Only thing is anymore, that you sniff where teamviewer takes connections with port 80 and block that ip
I would have to do a sniff, but from my understanding it runs on 80 and 443 but does not use the http or https protocol - so you should be able to use a layer 7 filter to block that traffic?
Just did a quick sniff of running it and it only used port 5938 outbound.. Could block that to see how it tries if that port is blocked.
Ok just blocked 5938 and it went out on 443, this time to master5.teamviewer.com but it was not HTTPS..
