Duping s2s VPN with NAT?

[#1]

Real dilemma here. Got two sites that need to be connected by a standard site to site vpn (policy or route). Only problem is both sites have the exact same subnet (192.168.100.x)!! I' m thinkin hiding each subnet with NAT would work, though I' m a bit shaky on the principles, and was wondering if anyone could offer any insight. Note:We cannot change the subnets address schemes. One more curve, its a pix and a fortigate. Any help GREATLY appreciated. Thanks!

Hello Kdillon, You may find some information in the following article : Summary : This article describes how to configure a FortiOS v3.0 gateway-to-gateway IPSec tunnel and use outbound NAT to allow connections between overlapped subnet addresses on both sides of the tunnel. http://kb.fortinet.com/kb/microsites/search.do?cmd=displayKC&docType=kc&externalId=12050 Let us know if this will help. -Remi.
