    I have a Speedtouch 516 modem in bridge mode and a WRT54GL with v4.71.1, Hyperwrt 2.1b1 + Thibor15c.
    How can I set it up so that I can access Speedtouch 516 modem's web interface by simply typing in a web address in the browser?
    I would like the WRT54GL's address to remain

    The speedtouch usually has a default web address of which would not be accessible from your LAN as the router thinks it is on the LANside. BUT I recall that some Speedtouch also respond on which is worth a try.

    If that doesn't work on its own there are a couple of Linux commands needed in your startup script (ifconfig ..., iptables...) to define an IP address on the WAN port of the router in the same range as that of the modem, and to use NAT translation to be able to talk.

    I don't use PPPOE full bridge mode so can't give you the exact syntax but others have posted examples before - hope this gives you enough clues to search!

    3 steps to be able to connect to a modem on the WAN side of a WRT54:
    - find the address of the modem. This could be,, or even could be a parameter somewhere in the config screen of the modem
    - connect to the WRT and add a STATIC route for that address to the WAN side
    - type the address in your address bar.

    I've done it for months and it works flawlessly. Only bemol in my case: my WRT gets its IP through the modem DHCP, so if the modem reboots, I need to renew that IP before I can do anything.

    Just add the following lines to your routers firewall script:

    iptables -I POSTROUTING -t nat -o vlan1 -d -j MASQUERADE
    ip addr add dev vlan1 brd +
