Feeding a load balancing router with another router

Hello. I am interested in using a load balancing router (one with 2 WAN ports) to have my home connected to both ADSL and cable internet infrastructures. The cable part is no problem, as I have a cable modem I can connect to one WAN port.

I seem to remember that ADSL modems with an ethernet connection were once common, but now I can't find any. All I can find are routers with built-in ADSL modems. In light of this, I would like to know:

1) Is it possible to feed the remaining WAN port with a modem-router? That is,
Cable line -> Cable modem -> WAN1
ADSL line -> modem-router -> WAN2

2) Is there any online store which ships internationally and sells simple ADSL ethernet modems?

Thanks.

It's not an ADSL ethernet modem that you want. You just need an ordinary router to connect up WAN1 and WAN2 to your WAN and handle the load balancing.

Hotbrick - many dual WAN routers
Cisco 1811
Netgear FVS336G

The Egg sells the Cisco's and the netgear.

If you don't want this device to do the load balancing, then perhaps an even simpler router would work:

Cisco 871 - single WAN port, 4 port switch on the other side.

Again - www.newegg.com.

I'm confused. Surely I need an ADSL modem somewhere if I want to connect to ADSL internet? I'm not sure if this applies worldwide, but in my case the connection is in the form of a telephone line with an RJ-11 connector.

Ordinary routers with a WAN port are easy to find, but I really don't see how they can help. I also have modem-routers with RJ-11 ADSL input, but it's still not clear to me if I can connect a LAN port of one of those to a WAN port of the load balancer (and whether there are any disadvantages to doing so).

Newegg also fails the international shipping criterion.

Now I understand.

d'oh! I thought for sure that the egg would ship internationally.

I understand more now. It seems you have a 2 port load balancer, and are looking for a router with a RJ-11 ADSL input on one side and the LAN port on the other.

Yes. You can do that. We do exactly that here. I have a "netopia router" thats a dsl modem and a router in one. Its output is to a 4 port switch labeled LAN - that goes into my load balancer. As far as addressing goes - its kinda odd but it works. I've got a 5 block of addresses per dsl line - the router gets one, and the load balancer gets one.

Mabey you can bridge the ADSL modem so it is just a adsl to ethernet bridge, but then you need to run PPPoE on that wan port.
