DNAT in freebsd

[Sami Halabi]

Hi, (sorry for sending again, the last email was with wrong subject)
I would like to perform a full dnat/snat as in iptbles in:
linux-ip.net/html/nat-dnat.html
How it can be done in fbsd, I use ipfw.

I seeked natd man page but its translation, and thr proxy_rule is for
specefic port, not a whole transparancy.

Thanks in advance,
