We have an internal router in our network with three hosts behind it. I need to know how to NAT an external IP address across our ASA - in essence to allow remote access to each host in turn behind the internal router. Is this possible? I've done single NATs to a single internal host, but haven't a clue how to do this with the internal router IP providing access to multiple hosts.
The internal network is defined as 172.16.0.0/16. The router is assigned an IP from this network. The hosts behind the router are network 192.168.x.x/24 (creating a private network within the local subnet).
What you suggest appears to be individual NATs for each of the three hosts. What I need is to NAT just the router IP - but through that single NAT - provide remote access to each host behind the router. It seems this could be done, but I'm not sure how to configure the ASA and/or the router for this set-up. Thanks.
