Working at setting up a VPN tunnel between two Netgear firewall units for two geographically separated networks. Can someone confirm or not, networks at both ends cannot be using the same IP addressing scheme.

Appreciate any suggestions and comments.

First, do the netgear support VPN? The low end models don't.

What model are you using?

NOTE: They have to have different IP scheme at each end to be able to route between them. It knows that everything on 10.1.1.0 network is at location A and 10.2.1.0 is at location B.

The units are FVS318 with capability of supporting 8 VPN tunnels. I can confirm both networks are using same ip addressing scheme. I'm sure that to setup the tunnel, one or the other network has to have a different scheme. But, as things go, it is better to ask the question than to assume.

In your comment you had the scheme difference in the second octet. Would this work on the third, ie
10.1.1.0 vpning to 10.1.2.0

????

Yes it would work to have something like 10.1.1.x/24 one network 1 and 10.1.2.x/24 on the second. While it is possible to split the same subnet between VPN's I strongly recommend having them separate like this to avoid routing headaches.
