Greetings Wise FreeBSD Gurus:

I can't seem to figure out how to accomplish what I want to do.  Can any
one help?

I'm running 3.2-RELEASE.  The machine is multihomed.  NIC1 = xl0 = RFC1918
internal net (192.168.1/24).  NIC2 = xl1 = cable modem IP (24.4.90.90).

I want to be able to connect to PCAnywhere running on an internal NT
machine (192.168.1.2) from my workstation at work (e.f.g.h).

I'm running natd and ipfw.

PCAnywhere apparently uses UDP ports 5631 and 5632 (but I've also seen
connection traffic on UDP port 22 which I thought was for SSH, but I
digress).

I thought all I would have to do is:

natd -n -xl1 -l -redirect_port udp 192.168.1.2:22
natd -n -xl1 -l -redirect_port udp 192.168.1.2:5631
natd -n -xl1 -l -redirect_port udp 192.168.1.2:5632

There we no errors from entering these commands.

IPFW started complaining about Denying packets, so I [temporarily]
alleviated that problem by issuing:

ipfw add 5 allow ip from any to any

Still no luck though.  PCAnywhere on my work machine just times out trying
to find a connection.

Can anyone shed some light on what I've done wrong?  I'm still pretty much
a newbie, so if I forgot to include some information necessary for
figuring out the puzzle please forgive me in advance.

And yes, I'm aware of other alternatives such as VNC.  I really want this
particular scenario to work, though.

Thanks in advance,
