    I like how the tag for this question also provides the answer. –  Jul 17 '09 at 11:47
  • It's migrated here from stackoverflow, but wouldn't it have been better to migrate it to superuser? – Peter Smit Jul 17 '09 at 12:31
  • He might be opening the company firewall to allow google talk – SpaceManSpiff Jul 17 '09 at 14:35
  • Any question that can be answered by typing it into google and reading the results page (not even clicking any links!) is a bad question. – davr Jul 17 '09 at 19:49

    gtalk no longer exists, and this question popped up for some reason. Not sure what do we do with obsolete questions, but it's not useful to have it open. – rvs Jan 06 '22 at 17:59

From Google Talk support pages:

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.

Port 5222 or 443.

That's what Google Talk says here: Google Talk Support

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.
