I have a Linksys WRT54G.

The Linksys is hooked to the switch via the WAN port. I would have put
everything on the same subnet but I can't see any way to make the
Linksys act as just an access point and NOT a access point/router.

The route table on the Linksys is:

Destination LAN IP Subnet Mask Gateway Interface
192.168.1.0 255.255.255.0 0.0.0.0 LAN & Wireless
192.168.0.0 255.255.255.0 0.0.0.0 WAN (Internet)
0.0.0.0 0.0.0.0 192.168.0.1 WAN (Internet)

The route table on the Linux box is:

Destination Gateway Genmask Flags Metric Ref Use
Iface
192.168.1.0 pool5.xxx.xxx 255.255.255.0 UG 0 0 0
eth1
192.168.0.0 * 255.255.255.0 U 0 0 0
eth1
24.xxx.xx.0 * 255.255.248.0 U 0 0 0
eth0
loopback * 255.0.0.0 U 0 0 0
lo
default cpe-24-xxx-xx-1 0.0.0.0 UG 0 0 0
eth0

Sorry about the wrapping.

So in this list anything going to 192.168.1.0/24 uses pool5.xxx.xxx
which is the Linksys.

Thanks for your help!
