To enable voice communications, make sure that outgoing TCP connections from port 6901 are enabled. Also enable UDP packets where either the source or the destination port is 6901.

To enable file transfers, enable both incoming and outgoing TCP connections to the 6891-6900 range of TCP ports. This allows each sender to perform up to 10 simultaneous file transfers. Note that if only TCP port 6891 is open, users are only able to perform one file transfer at a time.

To enable messaging, enable outgoing TCP connections to TCP port 1863.
