Firewall Wizards: Re: Blocking IRC ....

Re: Blocking IRC ....

Hello there, have you considered simply writing a rule which drops all packets from the
well known irc server ports such as 6666-7000? As well assuming you have control you may
simply want to lock down your users into using a company approved software baseline.
Doing this will also disallow them installing any programs as well unless they are
administrator.

Cheers!
