Firewall alerts of rouge Inet connection

[bdfrost @ centralplastics . com]

I have been told by several folks that it is possible to configure a
firewall to alert  you that whenever a rogue connection to the internet has
been created on your network. I don't want people doing dialup to the 'net
and going around our security procedures. I am using Firewall-1 3.0, but I
am not looking for Firewall-1 advice particularly, I just want to know what
a firewall would see that would alert it to the presence of a rogue
connection...


TIA,
Brian
