I KNOW there has to be a ton of examples but I'm unable to find them. The router is behind a cable modem and it gets DHCP from that. I can see the router get the DHCP but for some reason it won't route or is not subnetted properly. Maybe I've just plain screwed it up: for example, it seems like there are two DHCP addresses it gets.
