Site to Site VPN Same Network

I have an ASA5520 running 8.0.4. I need to create a tunnel with a vendor using the same internal network as we are. They are unable NAT on their side. I would like both sides to be able to bring up the tunnel. They are using 10.2.x.x/16 as their internal network, as are we. The interesting traffic on my side would come from the nodes 10.0.194.1 and 10.0.194.5. How do I configure my side of the tunnel to get this to work?

Thanks,

Keith

Re: Site to Site VPN Same Network

I don't think you'll ever be able to have both sides bring the tunnel up because of the NAT'd address space. Here;s is a config guide on configuring VPN with NAT (only 1 side can initiate).

Hope it helps.
