I'm having a problem with an ipsec tunnel.
Here is the situation:
My internal single IP for the tunnel is: 172.20.1.11.
My remote endpoint is 220.127.116.11.
(I'm only tunneling one IP on each network to each other)
Unfortunately, the remote network I'm connecting to has a lot of VPN
tunnels and they already have a tunnel to another network with an
internal scheme of 172.20.1.x.
Essentially, I need to establish the tunnel from one IP on my
network, to one IP on the remote network. Since they already have a
tunnel with someone else using my internal IP, I need to NAT
(essentially present it on their network as a different IP) my
internal IP over the tunnel to their network.
They have specified the NAT address I need to use, which is:
172.20.1.11 Needs to be Nat'ed to 10.0.200.129
Anyone have ideas if this is possible with M0n0wall?
