Help! I'm having the exact same problem.
I’m trying to configure a D-Link DCS-G900 Wireless-G Internet Camera for use with a D-Link DI-524 router.
I’ve assigned the camera a fixed IP address of 192.168.1.120 and added this address to the Static DHCP Client List in the router.
The camera has a built-in web server, on port 80. I’m on AT&T Yahoo! DSL and understand that port 80 is sometimes blocked. I’ve enabled Second HTTP port 81 on the camera.
In the router Virtual Server setup, I’ve set up port forwarding for ports 80 and 81 to the camera address (192.168.1.120), using Protocol Type BOTH.
When I run Look@LAN on 192.168.1.120 (the camera) it reports HTTP service on port 80 and hosts2-ns (HOSTS2 Name Server) on port 81.
I can successfully bring up the camera by entering either of the following into my browser:
http://192.168.1.120 or
http://192.168.1.120:81
I cannot bring up the camera on either port by entering my Router’s IP address into my browser, i.e.:
http://71.225.155.62 or
http://71.225.155.62:81
Any advice would really be appreciated!
One other note: I have a TiVo on my home network and have port forwarding successfully enabled and working with this D-Link router. I tried a Trendnet router early today with the same result (TiVo port forwarding worked, Camera port forwarding did NOT work).
One other question: The camera setup has a field for Default Gateway and DNS IP address. Should I be using the values reported by the router, or reported by my DSL modem? (Neither seem to work).
Thanks in advance!

Solved: The DEFAULT GATEWAY setting in the camera setup had to match my router's IP address: 192.168.1.1
