Ideally, I'd IP masquerading is part of the kernel changes in version 2.2, install the ipfw program and the /etc/sysconfig has entries on how to do it. FOr version 2.1.7 and lower, you have two choices: if you just need masquerading behind a ppp interface, Charles Mott has a set of patches and software up on his web site to do it at: http://www.srv.net/~cmott/alias.html otherwise if you need network interface-to-interface translation you have to recompile the kernel and add it in using software up on http://cheops.anu.edu.au/~avalon/ip-filter.html I'm facing the same problem myself, and I even tried out ipfilter, but the ruleset language is awful. Also, I'd be concerned about putting a lot of work into it and not being able to carry it forward to newer versions of FreeBSD. I'm currently waiting for 2.2 to go gold. Ted
