Why do I lose my internet connection when I forward all ports from one router to another?

Why do I lose my internet connection when I forward all ports from one router to another?

My DSL modem is a Siemens Speedstream 4200. It is not just a dumb modem, but also a fully-fledged router. I would rather it just act as a dumb modem and forward everything to my Linksys WRT54GL. I tried to do this by setting the Speedstream to forward all TCP traffic on ports 0-65535 to the Linksys, but then I could no longer connect to the internet.

I still don't know why forwarding all the ports breaks my internet connection, but the proper thing to do is put the router into bridge mode. It's quite simple. You simply navigate to [router's IP]/brgmode.htm and click the "Apply" button.
