I'm doing pretty much exactly what you propose, but I'm using DD-WRT in
place of the standard WRT54GL firmware. That allows me to configure the
WRT54GL as a wireless access point and 6-port switch, with all routing
and server functions performed by the Linux box that serves as a gateway
between my internal network and my cable modem. The router lives at
address 192.168.43.1. Yes, it would probably make more sense to put the
gateway box at the ".1" address and the non-routing "router" at ".2" or
elsewhere, but that's not how my network evolved.
Problem is that I don't have a WRT54 with standard firmware, so it's
hard to give instructions. As others have said, you would need to use
only the LAN ports on the router. Configure the router not to use DHCP
for its WAN connection and then you should be able to set up its local
IP address, subnet mask, and other network parameters manually. It's
hard to imagine a router that wouldn't let you do that. Yes, when the
router boots with its factory default settings it will be using
192.168.1.1, but you can temporarily configure your network interface
to talk on that subnet, log into the router, and configure it to your
liking.
