One-to-One NAT Incoming VPN Traffic on Cisco ASA5510

Hello,

We are trying to integrate a new vendor into our existing network via a L2L VPN but are having some issues due to a requirement that the VPN traffic needs to then be routed to a destination that requires it look like the traffic is coming from our local network.  Here are the specifics:

Inside Network:   10.30.64.x
Remote Network:   172.61.1.x
Destination:  10.30.64.15

We have the L2L VPN up and running, however the remote vendor can't access resources on the other side of the 10.30.64.15 router because it only accepts traffic from the 10.30.64.x network.  I am familiar with NATing the incoming VPN traffic to another network, but not to my local network.  

Question #1 - is it possible to NAT remote hosts (e.g. 172.61.1.9, 172.61.1.10, etc.) to specific IP addresses on my local network (e.g. 10.30.64.25, 10.30.64.26, etc.)?

Question #2 - if this IS possible, is anything required on my side, or will all configuration need to take place on the remote ASA?

Thank you!

Yes, you can use the static commands to the Nat on your side.

Here is an example and a link

L2L Example

Topology:

192.168.1.x/24 inside(ASA1)outside ===VPN===outside(ASA2)inside 192.168.2.0/24

If you were configuring ASA1 nat exemption for this L2L tunnel, it would look like this:

object network obj-local

     subnet 192.168.1.0 255.255.255.0

object network obj-remote

     subnet 192.168.2.0 255.255.255.0

nat (inside,outside) 1 source static obj-local obj-local destination static obj-remote obj-remote
