Checkpoint NG VPN same Network IP Scheme

[tester125]

Does anyone have any documents about setting up a Site to Site VPN's between two networks with the same Address scheme for Checkpoint NG. Of course I will need to NAT on one end. Checkpoint provided the documents but for the old version of checkpoint at:

I am running into problem using this document. VPN works great but without NAT.

THANKS for any inputs.
