Help with ASA site to site to site VPN's

In looking for examples for this type of info the only thing close to what we want to do is this URL http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00804675ac.shtml

We have a new third party company that needs access to our main site and the other VPN site.  We want to NAT the third party companies IPs (belgium).

Below our the configurations that we think are working. 

The configuration allows for Belgium to initiate communication.

Help with ASA site to site to site VPN's

Whichever ASA is the hub, you're missing the ACL that allows one remote network to talk to the other remote network. Looks like you're allowing it one way.

For example

access-list belgium extended permit ip 172.16.83.0 255.255.255.0 192.168.42.0 255.255.255.248

access-list belgium extended permit ip 172.16.1.0 255.255.255.0 192.168.42.0 255.255.255.248

access-list belgium extended permit ip 192.168.42.0 255.255.255.0 172.16.1.0 255.255.255.248

This may work for you but I've never seen anyone match access list in a crypto map with the same nat 0 ACL. If it works, that's pretty cool. Otherwise, you should have separate ACLs.

Good luck
