I think ipfw can do this.  At least the man page reads like it does.  There
is a "fwd" action which will change the next hop to something you specify.
I've been meaning to try it myself but just never had a reason.

Subject:        Port-based routing?

Hi,

Is there a way in FreeBSD to route packets based on the
destination port number?  (I'm asking this on behalf of
a friend, not for myself.)

This is the setup:  There are two uplinks, the first is
via a ADSL connection (ppp running on tun0, using PPPoE),
the second is via a normal ethernet interface (dc0, which
has a slower SDSL router connected).  They have different
IP addresses, of course.

Now he would like to direct web traffic (i.e. port 80) to
tun0, and everything else to dc0.  Is this possible with
FreeBSD at all?

Thanks in advance for any hint and advice!

Regards
   Oliver
