Actually it's vice versa, it's if clients are behind NAT connecting to
a m0n0wall IPsec mobile VPN server. Doesn't matter if it's m0n0wall
NAT or any other type of NAT. I think there are exceptions to this
with certain NAT implementations with IPsec proxies (at least there
seem to be some exceptions, though no details on those exceptions, so
I'm just guessing).
As far as site to site IPsec, I believe that works when either side is
NAT'ed. I seem to recall some people using it that way.
as for clients behind m0n0wall, see this thread:
