I also looked at https://help.ubuntu.com/community/IptablesHowTo
You need to start the service that listens on port 6667. Just opening the firewall doesn't help if there's no service listening on that port.
thanx i installed an irc server and now my system listens to that port. <<< what do u mean with this ? can u tell me more , cause i have some problem with u my be more. when i run psybnc its run but just for a minutes its dropped again , the connection refused again . so i decide to stop the process of iptables but its bad . pls advice
