Isn't this an example of split DNS? Normally I would have a DNS server running on the LAN with a forward lookup zone that will resolve a name to an *internal* address. I am not familiar with that router but have never seen a DNS server built into a cheaper router that could handle this correctly.

Sorry, my questions are usually much more targeted at enterprise environments but this morning I'm thinking about my home set up. I've downsized a lot recently. From running Hyper-V on two dedicated 2900's and 2950's and PFSense on a dedicated appliance I've gone to running just one Linux server on a cut down Asus system. I had to do it for a number of reasons but basically, it was becoming too difficult to manage and do everything else as well. I'm encountering a limitation of my newly purchased Belkin router. It's an N600 and for various reasons it doesn't support any variant of DDWRT. external services are running fine thanks to it's port forwarding / virtual servers or what ever terminology it wants to use. So, on the internet I can access systems on port 80 or 443 etc. The problem is that inside the network, I cannot access these systems. I know that DNS etc is working fine because if I ping one of the hostnames it resolves to the public IP but if I try to access the system using http for example the traffic never gets to the server. I'm assuming it's getting stuck at the router side. The router is likely not forwarding traffic origionating from an internal address back through the router to the internal server. Weird ay? Any ideas?
