one modem one connection 2 networks

Specs: Windows XP
I have 1 DSL modem going to a switch. Switch has two
ports. One port going to a linksys BEFSR41 (router #1)
with a ip. It connects properly to the modem
using PPOE. This works well.

The Other port goes to another Linksys BEFSR41 (router
#2)but with an ip of I am trying to get
it to connect to the DSL modem but to no avail. as far as
i can see - same settings on both Linksys.

My objective: Router #1 goes to a hub with many computers
attached to it. I want to put an access point on router
#2 and allow only internet access traffic, so that trafic
on router #2 wont be able to access any computers behind
router #1

Do I have a defective router ? or cant this be done with
this setup?

I suspect that your DSL modem is only capable of connecting a single device to the Internet. If you disconnected router #1, after re-booting the modem you would probably have no problem connecting router #2. But, then you wouldn't be able to connect router #1. Just remove the 2-port switch and plug router#1 WAN port directly into the modem. Then, plug router#2 WAN into one of the LAN ports on router#1. Configure #2 with different network than #1. Providing that there is no network bridging enabled on the routers, the networks will not be able to communicate with each other, but router #1 should forward Internet traffic back and forth to router #2.

If you want two ips from the modem you need to contact your isp and buy the additional ip. Then your setup would work.
