ip_fil3.1.1 compiles and works under FreeBSD, supplying full NAT support
although I havn't got the ftp-data stuff working yet - I think that'll
have to proxy.

If you're looking for a "cleaner" solution,

    http://www.srv.net/~cmott/alias.html

will give you a NAT-like iijppp program, and an even cleaner solution,
socks5 (one of the ports - and maybe a package) will give you a socks5
proxy solution.

: ps/ Also, what is the status of DosEMU (or the equal) for FreeBSD?

I have a dosemu binary on one of my FreeBSD machines, but I've never
used it.
