How to configure linksys routers to route to an AP600 bridge?

I use a linksys router and a chain of other equipment to extend the wireless signal to the mission house. I want to configure the WRT54 linksys router to route the signal to our Proxim AP600 access point. The first router is assigned the Static IP address, 192.168.1.1 and the AP600 access point Static IP adress 192.168.1.2. The AP600 settings are just fine. I need to change the default settings on the new WRT54 router so it connects with the AP600. I need step by step instructions on how to achieve this. We use wireless only after the first router.. Please help
