I'm looking into moving VPN Lan to Lan tunnel configuration from Cisco 3000 VPN concentrator to ASA 5510. I noticed that this particular configuration has NAT enabled in the concentrator (Config => Policy Management => Traffic Mgmt => NAT => L to L Rules)... there are 2 servers NATted to 192.168.1.1 and .2 addresses, so I need to do the same in ASA. What steps should I take to achieve the same config in ASA? Can this be done thru SDM?
In ASDM => configuration => NAT Rules, I can create static rule from Inside interface to Inside int, and then create the tunnel using "translated address" or "translated network" as Local network in VPN config. Is it correct?
That is correct.
You should NAT the traffic of the VPN and define the VPN traffic from the translated addresses.
