I’m having an issue and I’m not sure how to approach it. I have a Site to Site VPN setup between two locations which is working fine. On my side of the connection I’m working with an ASA 5512x running 9.9(1)2. I’m not sure what FW the customer is running, but it’s not Cisco.
As I mentioned the Tunnel is up and traffic is passing except for two hosts. On my end for the Local Network I’m allowing 6 IP addresses:
The Remote Network on the customer site the interesting traffic is:
The issue is with the 10.2.1.15 and 10.2.1.16 hosts. They are not on my local network. They are on a network I connect to through an MPLS line. The customer can connect to everything except them.
My question is how do I allow the 172.16.16.xx, 172.16.17.xx Hosts to access the 10.2.1.xx hosts through the VPN? On my network all the hosts on 10.1.1.x can access the hosts on 10.2.1.x with out any issues.
I assume I would have to do a NAT and possibly an ACL to get that to work? I would appreciate any help on this.
