Setting up a web server with Netgear WGT 624 and Netgear 632

Hi all!

I've been using since last year a wireless router Netgear WGT 624 with
an ADSL modem Netgear 632. My Lan is made with 2 PCs.
I had some trouble configuring it some time ago but after that
everything worked fine with an excellent connection.

Now I've been thinking of putting up a web server at home using the
sites that let to use dynamic DNS.

I was trying to test my configuration to see if it was working fine
before registering to one of these services. I installed Tomcat on my
main PC. Locally I can see it. Then I set a port forwarding on the
router (624) for HTTP pointing it to the PC where Tomcat is installed
and running. When I try to call from a web browser the dynamic IP
address that my ISP is giving me in that moment, I see the admin page
of the modem (632). It is like the router forwarding isn't working at
all and the modem is answering to that request.

These are the router and modem configuration:
