    I have a cisco DSL router with does natting and I have connected RT N-16 with tomato firmware installed for QOS. The thing is I just dont want to use double NAT instead i want that my cisco does the natting and Tomato does the QOS. Is this setup possible ? Any ideas ?

    I have tried to setup it by making the tomato router in router mode but no success. Also I would like to know how the WAN port functions in router mode.

    In router mode the router should just route from lan ports to the wan port BUT many tomato functions and most development has been on the assumption that the tomato router is a nat gateway, this includes IP accounting, firewall rules, port-forwarding, UPNP and probably QOS. I guess it would be unusual for a router in 'router mode' to also be the dhcp server/ dns proxy, so you either need to ensure all static IP addresses or pass-through to higher device works properly. So router mode reduces the router to little more than a configurable intelligent switch.

    I have seen some posts where users are using 'router mode', but they used a lot of custom rules in firewall rules to set routes etc, when I last tried I couldn't get it to work, so opted to set up slave device as an access point connected via LAN, the web gui option to 'Use WAN port as LAN' then allows you to have 5 LAN ports.

    Thanks mstombs for your reply. I am not quite sure how the router is behaving in router mode. Devs may give some input so that we can be sure about the working procedure in router mode.
