My ISP has supplied me with a modem/router all in one and it isn't very good. It loses its settings and dies frequently. So I have another router in my apartment (Linksys wrt310n) that is connected to the modem via LAN->LAN port connections.
I want to give my Linksys router the DHCP role and also have the ISP modem DMZ everything to the Linksys router. I want to be able to have all computers connected to both routers on the same network as well.
I have been able to make it so that the Linksys has a DMZ to it from the ISP modem, but ISP modem LAN port -> Linksys WAN port, so they were on different networks.
Is there a way to have it so that both of them are on the same network but the Linksys router handles DHCP and port forwarding?
