Opening Firewall Ports for iChat Service

iChat requires specific ports to be open on your server. If you have a firewall configured or you are using the Mac OS X Server firewall, you must enable these ports before you can use iChat.

Depending on the iChat functions you require, make sure the following ports are open.

Ports	Description
16384-16403	iChat audio/video RTP and RTCP
5060	iChat Session Initiation Protocol
5190	iChat Instant Messenger, file transfer
5222	iChat Server
5223	iChat Server SSL
5269	iChat Server server-to-server
5297, 5678	iChat local UDP
5298	iChat local
7777	iChat Server file transfer proxy

If you run iChat service on a secure network behind a firewall, you don’t need to configure firewall settings as long as communication between users is within the network. Firewall settings are required when communicating outside the firewall.

For more information about the Firewall service and settings, see Network Services Administration.
