Cisco ASA 5510 Dynamic nat

Good morning everyone,

We currently have a VPN setup with a client. We now need our home users to access their resources as well. Normally I can just add the home users pool (192.168.253.0) to each end of the tunnel, however the client already has a VPN with a 192.168.253.0. So, my idea is to have the 192.168.253.0/24 translated into 10.66.253.0/24 when it tries to hit the client side (192.168.100.0/24).

I'm pretty sure I need to setup a Dynamic nat policy, but I haven't really done this before. Any help would be beneficial! Thanks

What version of ASA do you have? If you have 8.3 or later you can use twice nat. Example:

Depending on the complexity of your ASA and network, it might be easier to just change the VPN client pool.

8.2. I could do that for the one client, but our network is pretty complex. I'd have to change about 80+ tunnels to if I change the pool.

Could I do something like..

access-list Exempt permit ip 10.66.253.0 255.255.255.0 192.168.100.0 255.255.255.0
global (inside) 2 10.66.253.0 netmask 255.255.255.0
nat (inside) 2 access-list Exempt

And Of course, add the 10.66.253.0/24 to the tunnels.
