Clients can't connect

[Phonetic]

Hey there I used to have a Windows machine running TS2 on it and that's what my friends and I would use, but I decided that I'd rather run everything on Linux. I have everything installed and configured, the only problem is that I can only connect on the server machine, clients cannot. Thinking it was a firewall issue I disabled SELinux, but I'm not sure if there are any other firewall or security options such as selective services. Does anybody know how to make it so that my friends can connect, and how to disable security options?

Thank you in advance.

The firewall is called "iptables". SELinux is not a firewall, it's rather some kind of kernel extension, but it might be an issue as well.

Just open a terminal and type "iptables -L" to see all firewall rules applied. If the output looks similar to the following, your firewall is configured to allow any traffic (incoming, outgoing and forwared).

Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

If your output differs, you have to add a new rule for teamspeak or disable the filewall.
