This is a multi-part message in MIME format. ------=_NextPart_000_001A_01C0BDF4.F34C2EE0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable I am using FreeBSD v3.2. I am using ipfw and natd. I would like to = forward inbound ftp traffic to an internal server. I have tried ipfw fwd = unsuccessfully. The rule I tried: ipfw add 200 fwd 192.168.4.2 tcp from any to <oip> ftp Where 192.168.4.2 is the internal ftp server and <oip> represents the = public address on my ipfw firewall. Am I misunderstanding the function of fwd? I have not tried natd = -redirect_port yet. Would this be a better option? fwd could be added or = removed dynamically (preferred). Any suggestions are welcome. Thanks.
