Hi Experts!  I have 2 dynamic dns host names that point to my router (dd-wrt).  Lets say:
sub1.domain.com  and sub2.domain.com
with port mapping, everything works fine with external calls to these hosts

internally, I'd like map these hosts to internal IP addresses.  so if a request goes out for a webservice that sits inside my firewall, I don't want the request to leave the router just to find out that it points back to the router.  I can think of a few ways to do this:
1. can i tell my router about sub1.domain.com... and tell it to always route those requests to the appropriate machines?
2. maybe I can tell each individual machine about sub1.domain.com... and specifcy which internal IPs to map each host to?

not sure what the right approach is nor even the right vocabulary about how to discuss this issue.
