i have ASA 5505 and have typical situation which some low cost routers allow, but i cant find how to do it on ASA.
What i mean. ASA is router/ firewall with NAT. On internal network is some clients and 1 server. This server hosts HTTP server and DNS server.
DNS server ahs records for external domain www.domain.com which is this same server in fact but this record is for external users and internal users as well.
On ASA is configured static nat with PAT from port 80 to port 80 from server IP to outside interface IP. This redirect works good for external users.
Internal user request in browser www.domain.com, he got ip address 18.104.22.168. Browser try to access 22.214.171.124 But with no response from ASA because ASA dropped traffic by ACL. But ACL is configured on inside interface from any to any protocol ip permit.
I want that ASA redirect this request back to inside interface and show this page to internal users. On low cost Ovislink this works.
What can I do for that so internal users can access web server on internal network but by external IP address? This situation is in more companies that I know and I still dont know how to resolve it.
