I think, I did not understand the ipsec nat-t issue correctly...
Let us assume the following configurations:
Homenet - m0n0 - internet - nat-router - roadwarrior
Homenet with 3rd party vpngw - m0n0 - internet - nat-router - roadwarrior
To my mind, nat-t is needed in setup b) where the roadwarrior tries to
connect to a vpn-gateway behind m0n0wall.
Setup a) is what I did not manage to get running. Why is nat-t needed here?
Is setup a) possible with m0n0 1.21?
The documentation says
"m0n0wall does not support NAT-Traversal (NAT-T) for IPsec, which means
if any of your client machines are behind NAT, IPsec VPN will not work."
Which client? The roadwarrior, or some client behind a m0n0wall trying
to connect to some remote vpn-gateway?
Hopefully someone can enlighten me :)
Thanks in advance,
