iptables and IRC clients.

Hi, im new to irc.
whenever i attempt to join a room, the room apears empty, but my firewall hit-log goes mad. it seems my firewall is blocking essential traffic.

also i noticed an ip_conntrack_irc kernel module. which seems to be used to allow
file transfere's via the state related rule.

anyway...
what ports and protocols do i need to allow on the INPUT chain for IRC to work correctly ?

thankyou.

The /etc/services file should have the info you need:

Code:

# grep -i irc /etc/services
irc             194/tcp    #Internet Relay Chat Protocol
irc             194/udp    #Internet Relay Chat Protocol
irc-serv        529/tcp
irc-serv        529/udp
ircs            994/tcp                 # irc protocol over TLS/SSL
ircs            994/udp
ircd            6667/tcp   #Internet Relay Chat (unoffical)
