OT : Help an ADSL Newbie with Port Forwarding

[deccan]

Some of you may remember me asking for advice on software to use with my new always on connection. Well, it's finally up and running now but I'm trying to get port forwarding to work right.

Right off the bat, I'll say that I can get it to work fine if it's just:

Internet - ADSL Modem / Router - Me

But right now, it's:

Internet - ADSL Modem / Router - Wireless Router - Me

And the same trick doesn't work anymore? What do I do in this case? I tried forwarding the ports I needed from the modem / router to the IP of the Wireless Router (that I got by looking at the modem / router's configuration page to see what is connected to it, in this case, just the one wireless router), and then forwarded the same ports on the wireless router to my internal static ip, but it didn't work. Is there something else I should know about?

Thanks.
