I'm looking to connect 2 networks that have the same IP's and subnet (192.168.0.XXX/24). I'm not looking to completely merge these 2, but I'm looking to setup a VPN for about 2-3 computers to run on SITE A's network and have access to SITE B's Server. SITE A IP scheme is 192.168.0.XXX/24 and SITE B's is 192.168.0.XXX/24. SITE A, the site the 2-3 computers will be on. SITE B, the site where the server will be. My problem is SITE A has a DHCP server and a DATABASE server (the database server is the same as SITE B's server!?) I've not setup type of VPN for this connection to happen yet, I'm just looking at the best possible way for this to happen. SITE A has an ASA 5505 on it and SITE B has an ASA 5510 on it. both sites have multiple site-to-site VPN's already setup on them so changing the privet IP scheme is not really a timely option. I was woundering if there was a way to NAT SITE B's server to maybe something like 10.10.10.1 on the ASA 5510, but still be able to access it through it's normal IP (192.168.0.XXX) locally and through the other already setup VPN's. If I can do it this way I can just static the 2-3 computer on SITE A's side and create a normal site-to-site VPN, but only allow them access to 10.10.10.1. Is there a way to do this or has anyone ever ran into this problem and has a fix for me?

Thanks. We'll let you know when a new response is added.

Madpawn, please see my answer on your previous question about this. It is perfectly possible, and I put the nat commands there. It source nat’s the PCs and destination nats the server. All you need to add is the VPN config, based on the nat IP’s and not on the ‘real’ ones, and it will all work.
