See Matthew Seaman's post on this - I think he knows more about this than I do ;) I remember using snort for something recently and don't remember encountering any problems - It shouldn't need to be assigned an IP AFAIK. > Andrew, do you like VooDoo Blue?

I downloaded a couple of MP3s from the site and they are pretty good :) Not sure if their music ever makes it to Scotland though, which is where I am! > -----Original Message----- > From: Andrew Boothman [mailto:andrew@cream.org] > Sent: Saturday, January 03, 2004 12:27 PM > To: Scott Renna > Cc: freebsd-questions@freebsd.org > Subject: Re: problem with 2 nics in same box > > Scott Renna wrote: > > >>Hello List, >> >>I am having some difficulty in getting my xl0 and xl1 3com cards to > > work > >>the way I'd like.
