Help setting up Wl-520GU with tomato

    I have successfully flashed from dd-wrt to tomato usb.

    My configuration is as follows; modem (SmartAX MT882)is connected to wan port of 520GU, then desktop is connected via a wired connection from a 520GU LAN port.

    The problem is my desktop pc can't connect to the internet. Can anyone help changing some settings on tomato (and maybe my modem?) to get internet working over LAN.

    tomato settings are currently default etc.


    On tomato:



    router ip:

    On the modem I enabled bridge mode I believe this would be a first step.

    It was a fairly simple setup with stock firmware on wl520gu to get internet working, but I have know idea on how to get internet working now that I'm running tomato usb.

    Does anyone have any ideas. I'd imagine it would be fairly simple.

    You need to use a different IP range on LAN and WAN, so change Tomato to for example - otherwise router doesn't know where to route packets.

    You will also be running "double nat", which is probably all you can do in NZ with pppoa and that modem. To get port-forwarding etc to work on Tomato you need to assign the Tomato WAN port to be the dmz of the modem.

    Thanks for the reply mstombs,

    If I understand correctly "double Nat" is when both the modem and my wifi router have NAT enabled.

    I think I'll probably be able to figure out ip ranges there will be two different ranges right? So (dhcp .2-50) and (.2-50) would these work?

    I'm pretty sure your right about no pppoe, I'm in a non-asd2+ area.
    I'm not understanding the "dmz" part can you try to explain how I might set this up.

    I have found settings for dmz in the NAT configuration menu. It has the following options virtual server: pvc0-pvc7, and an option to choose single or multiple ips. Then when clicking dmz, it asks for a DMZ host ip address.
    Which address would I enter for Dmz host ip?

    Forget all the crap in my above post. Internet is finally working. (YES!!!)

    I set up Dmz to and basically that was all i had to do. Couldn't believe it was that simple.

    Cheers, for the help mstombs.
