Re: VPN between two companies - same subnet

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

NAT the traffic before it crosses the tunnel. For example let's say your
both 10.0.0.0/24. You can NAT all your traffic going across the tunnel to
appear like it's 10.2.0.0/24. The other side sees you as 10.2.0.0/24. This
has to happens on both ends to work properly.

real address -- nat address **V P N T U N N E L** nat address -- real
address
10.0.0.0 10.1.0.0 10.2.0.0
10.0.0.0
