I have a Cisco ASA 5505 that I need to configure for a VPN (LAN-to-LAN) connection between a local office and a remote facility. The problem is that the remote facility is requiring me to use a different IP address for the local server, so I am assuming NAT needs to be involved.
Basically, a single local server (LOCAL_SERVER) needs bi-directional communicate with 3 remote servers (REMOTE_SERVER1, 2, 3). The remote servers need to "think" they are talking with a translated address (LOCAL_SERVER_NAT).
My present configuration is not working and I don't trust that I have the config correct. Can someone please examine the config and tell me what needs to change?
TIA

access-list inside_nat_static extended permit ip host LOCAL_SERVER object-group REMOTE_SERVERS
to
access-list inside_nat_static extended permit ip host LOCAL_SERVER_NAT object-group REMOTE_SERVERS
and create another acl..something like this:
access-list inside_nat extended permit ip host LOCAL_SERVER object-group REMOTE_SERVERS
and use it for the static:
