I've noticed that on some of the low end non-cisco dsl/cable routers that there is support for DNS NAT Loopback where:
A router is performing NAT for a web server (internal ip - 10.10.10.10, external nat - 122.1.1.1), the DNS entry will refer to 122.1.1.1...
Another user on the same 10 intranet wants to access the website via the DNS name. From our experience, this doesn't work unless you use split DNS or add an entry to the internal users hosts file.
Do cisco routers support this functionality, if so, how can this be configured?
