Hmm, hier zit m'n zusje dus ook over te zeuren

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.
Ik moet dus 6891-6900 openzetten, maar die staan open in mijn firewall... Ik moet ze alleen mappen (toch ?

). Alleen: welke port naar welk ip (ik heb 5 users achter een IPTables NAT server) ?
/me is op dit gebied nog een heeeeel klein beetje n00b
