Right now I have a PHP script running a socket server on my server with flash as the client. Everything works fantastically except that the chat doesn’t work for about a fourth of the users. I’ve never had that problem and it’s always the same users. I suspect it’s a firewall issue, but my question is how do I get around that? Are there any ports that I can use that won’t be blocked by even the strictest of firewalls? And if it’s not firewall problems, then what else could it be?

If you are getting any packets at all from then it’s not a problem with firewalls. TCP will go through most anything since the client is beginning the connection. Your problem lies elsewhere.
