Hi Vinay, How did you "open a port"? Did you create a Protocol Rule that allows outbound access to TCP 6667? Thanks!

I have a secure NAT client and would like to connect to IRC server. I have already opened TCP port 6667 for both inbound and outbound but still no luck. Please advice as what other configuration is required for IRC to work behind ISA. Regards, Vinay.
