Help with ADSL modem and DD-WRT router

[One More Solo]

I'm making my first venture into networking beyond basic wireless access points and connecting a modem (Zyxel P660R D1) to a wireless router (Linksys WRT54GS2). I've got the two talking and the internet is working without any problems. I couldn't get the modem working in "bridge" mode so it's currently in "routing" mode, connecting to the internet via PPPoA. The router gets the WAN IP via DHCP which is enabled on both.

I'm not sure this is the right way to do it! I'm trying to get my PS3 to display an open NAT and have forwarded ports on both the modem and router but neither worked. Can someone help clear up the mess I've made?

There is a bridge mode but for whatever reason it won't connect to the internet set in that mode.

The router's IP is always static is it not? e.g. 192.168.2.1 I've added that address to the DMZ and will see what happens.

Cheers, will have a look. Do I need DHCP enabled on both?
