Port Forwarding on Daisy Chained Routers

Specs: Windows XP
I recently purchased a Zonet wireless IP camera. It works great within my network but I'm trying to get it to work externally. Here's my setup:

Internet --> Grandstream VOIP Adapter (HandyTone502) --> WAN port on BEFSR41 Router (DHCP enabled) --> Port 2 to Port 1 on BEFSR41 Router#2 (DHCP disabled) --> Port 2 to Port 1 on WRT55AG Wireless Router (DHCP disabled) --> Wireless IP Camera

It would seem that port forwarding would be pretty straight forward considering everything is on the same LAN, but I can't get it to work.

Internet works fine with this setup. Again, the IP Camera works fine internally.

I've forwarded port 1024 to the internal IP of the web cam (both UDP and TCP) on the VOIP adapter and each of the routers. However, when I enter my external IP address (IP address of the VOIP adapter):1024 (i.e. 11.2.33.444:1024) it times out.

I also tried forwarding port 1024 on the VOIP adapter to router #1 internal IP, then router #1 to router #2 internal IP, then router #2 to router #3 internal IP and router #3 to IP Camera - that didn't work either.

The user manual for the IP camera suggests the following: "We suggest to use port 1024~65535 if the camera sits behind a NAT router or firewall" I assume that pertains to me so I forwarded 1024 (or at least tried to).

Any suggestions? Thanks.

Ok I guess I'll ask the stupid question first....why the second SOHO router? Why not just use the Grandstream device and plug a switch into it?

Your post is confusing. First you say:

It works great within my network but I'm trying to get it to work externally.

and then later I see the following:

I've forwarded port 1024 to the internal IP of the web cam

I've never heard of a device that can be both internal and external at the same time!

Where is this camera located with regard to your LAN and the SOHO Router (grandstream) and what is it's TCP/IP configuration? The term external means 'outside of your LAN' which would put the camera out on the internet somewhere.

A typical port forward means you forward the port of incoming traffic to an internal IP.
