TomatoUSB

Hi all.

I'm new to Tomato, and somewhat new to router config. I'm trying to setup what I believe is called a downstream router. I have a fairly standard gateway box running Merlin that provides NAT, DCHP, etc. I want to use a Tomato box for QOS. For reasons to annoying to mention, I can't convert the gateway to Tomato.

I'd like to go from the gateway to the Tomato box, then out to the LAN. I assume I need to go into the WAN side of the Tomato box to get QOS. I'd also like DHCP to pass through the Tomato box and provide DHCP for the LAN-side clients - everything on 10.0.1.0/24.

When I put Tomato in router mode, I can't get through the box.

Any suggestions? I'm open to any configurations that keep the gateway in place and running Merlin.

I have a feeling that I'm making a newbie mistake here. This seems like something lots of people would need to do. Is it a mistake to even try to do this?
