Hi guys. I'm trying to set up a firewall on a box for a friend. The arrangement is fairly simple, bunch of machines behind the FBSD box, FBSD box connected to ADSL. What I'd like to do (because I wanted to in the first place, and now it's annoying me) is to have 2 Ips on the external i/f on the FBSD box, and have one as the machine's primary IP and t'other solely as the NAT IP. I've tried putting various Ips in the places that make sense to me, but I just couldn't get it to work[1]. Is this possible, and if so, would someone be so kind as to tell me how? I'm trying to move over to pf from ipfw, and if I can get it working, I've got a strong case for using it at work as well. Thanks in advance for your sage advice. :) Cheers, Aled. [1] This is just one place where I prefer linux's eth0:alias1 type labelling of sub-interfaces over FreeBSD's just-put-multiple-ips-on-one-interface way.
