Re: [FW-1] VPN to firewall behind NAT

quick question: is it possible to set up a VPN using Checkpoint
VPN-1 NG (FP1) with a firewall that is behind a router doing NAT?
i.o.w:
fw (e.g. 1.2.3.4) <--> (e.g. 5.6.7.8) NAT router (e.g. 10.0.0.1) <--> fw (e.g. 10.0.0.2)
Is this possible using IKE and IPsec? I vaguely remember IPsec uses
the ip-address of the firewall for some hashing so this will
probably get messed up when using NAT right?
It is possible as long as both VPN endpoints support UDP encapsulation
of the IPSEC traffic.
