FTP Proxy

[jean-francois_(_dot_)_gobin_(_at_)_nrb_(_dot_)_be (Gobin Jean-Francois)]

Having tried many many many way to make FTP works with IP Nat, I decided
to forget the "ipf/ipnat" way and install a FTP proxy on my OpenBSD FW.

But ... Does anyone know a good FTP Proxy (It has only to make a
redirection from my fw to my internal FTP server, automatically if
possible), that _compile_ under openBSD. I found many of them .. but can
not compile ...

Thanks in advance,
Jean-Francois
