Just block below ports...

* What ports does Google Talk require? *

 If you're having trouble connecting to Google Talk through your firewall or
proxy, it may be because some necessary ports are blocked.

In order to connect to Google Talk and start sending IMs, you'll need to
enable TCP connections to talk.google.com on port 5222, or on port 443.

If you'd like to make calls or transfer files through Google Talk, you need
to:

   - Enable UDP connections to anywhere on any port; or
   - Enable TCP connections to anywhere on port 443.

If you're behind a public or corporate network that is blocking these ports
or protocols, please contact your local network administrator for further
instructions.
