I want to host a small personal website at home. One basic problem I am hitting is, From inside home network, I cannot access my domain name. I have to use the local ip (something like 192.168.1.4) to access the website. This ip is the desktop which is hosting the website. Because of this mapping, I have issues setting up a simple wordpress blog on it too.

How do I get past this issue?

edit:0 when I try to access www.example.com (my domain) from within my home network, I get redirected to my router login.

PS: 1) I am using dyndns service to map my non-static ip to my domain name. 2) My portforwarding works fine.
