Thanks,

I was pretty sure that I was on the right track.

Just for clarification:

"..., and run an IPSec 'helper' module (with 2.2 kenels...I'm not sure if
the 2.4 kernels work the same way) or use nat-traversal (which 'tunnels' the
protocol 50 traffic across UDP)."

This refers to the internal machine running the ipsec server.

There is nothing that has to be added to the Bering firewall box.  Right?

(Basically, all the firewall sees is the UDP packet, which it just
port-forwards like anything else.  The NAT-traversal "patch" is applied to
machines at both ends of the ipsec tunnel, not the firewall/NAT-PAT
machine.)

Thanks - Ted
