Hello,

I have a m0n0wall router at an offsite location that is behind another
firewall.  It is set up with a non routable IP on it's wan interface
which is connected to a public IP by a 1:1 NAT from the site's primary
firewall.

I would like to be able to do IPSEC connections with this unit, but I
need to tell the site admin what ports/protocols he needs to open up
for this to work.  I was unable to find this information in the
official m0n0wall docs and I was less than successful in finding the
right mix of keywords to search the mailing list.

Any assistance would be appreciated.
