Need some help/clarification on my port forwarding setup

[SaltBoy]

Okay, I have two "routers" - a Vonage V-Portaland a Linksys WRT45G - and a very non-frills, basic setup. My computer connects to the WRT45G, the WRT45G goes to the V-Portal, the V-Portal goes to the cable modem, and the modem goes to the internet. Nothing out of the ordinary, right?

Now boys and girls, let's pretend that my regular IP Address (that the internet sees) is 123.456.789.123.

The IP Address of the V-Portal is 198.162.15.1 and recognizes the WRT45G's IP Address as 192.168.15.2.

The IP Address of the WRT45G's router is 198.162.1.1 and recognizes my computer's IP Address as 192.168.1.105.

On my computer, I have UltraVNC installed. UltraVNC uses port 5800 for http-based viewer requests and port 5900 for VNCViewer requests.

On both the V-Portal and the WRT45G, I have port forwarding set up. Both port 5800 and port 5900 on the V-Portal forward to 192.168.15.2, while both port 5800 and port 5900 on the WRT45G forward to 192.168.1.105

While on my computer, when I type in either http://127.0.0.1:5800 or http://198.162.1.105:5800 into my browser's address bar, UltraVNC loads up just fine. It's (obviously) kind of silly because I can see in my browser what I'm doing on my computer, which is looking at my browser, and so forth.

However, when I type in http://123.456.789.123:5800 into my work computer (or home computer, for that matter), nothing happens. I have set up also a dynDNS host for my IP Address and the http://hostname:5800 address doesn't work, either.

When I type in 192.168.15.1:5800 (or 5900) from my home computer, nothing happens

When I type in 192.168.15.2:5800 (or 5900) from my home computer, nothing happens

When I type in 192.168.1.1:5800 (or 5900) from my home computer, nothing happens.

I tried this with firewalls both on and off.

So, I'm thinking that the port forwarding on the WRT45G is broken, but I'm not sure if I have my forwarding setup correctly. Any thoughts on this? Am I typing in the wrong port on my internet-based address?

There is No point to have two Routers.

Configure your WRT54G to work as a switch with an Access Point.

I believe port forwarding only works on incoming WAN requests, so I wouldn't worry about what happens on your home computer/local network.

I think this part is your only real problem. Can you ping 123.456.789.123? Or hostname? Also, the cable modem could cause some interference as well (or are you sure that it doesn't?).

Edit: wording

Your setup needs be changed. Hook your WRT54G router's wan port to your cable modem, then hook your computers AND your v-portal (internet port) to a LAN port on the WRT54G. Don't plug anything into the LAN port of the V-portal. Then do your port forwarding on your WRT54G router and your done. The V-portal CAN act as a router but in your setup, no reason to do that as it just complicates things more.

Guys - just following up here. I took kevinch2's advice and moved the vportal to one of the ports of the WRT45G. Everything now works like it should - thanks!!
