Using Versalink 7500 as modem

    Hey, I've been getting tired of the terrible modem/router that Verizon sends by default, so I bought a WRT-54GL and installed tomato on it.

    Now, I still need to use the Versalink as a modem, as the WRT does not have a DSL input, but I am having no luck getting this to work.

    The installation went flawlessly, and I disabled DHCP on the Versalink, but still no luck getting any internet on the WRT. I can access other computer on my LAN on the WRT, just no WAN.

    One item of note; the Versalink is, by default, using a routed bridge mode. I tried switching to bridge mode, this didn't work. I am also not sure between which ports on the two router I should run the ethernet cable.

    Any help?

    The modem should be plugged into the WAN port on the GL. Remember that you need to set up PPPoE on the router, since that function will no longer be handled by the modem.

    No luck, Verizon uses DHCP in my area, no PPPOE. In theory, this means that tomato should be plug and play, but theory never agrees with reality...

    I've tried to set the Versalink 7500 in both routed bridge and bridge mode, but neither worked. If the Versalink is set with DHCP enabled, tomato finds its private IP easily enough, but devices attached to the WRT cannot connect to the internet with the double NAT.

    Any other ideas?

    Have you given the WRT a STATIC IP on the Versalink 7500 and also DMZ that STATIC IP too?

    Are DNS IP's correct too?

    Make sure the Tomato router uses a different local network address on its lan and wan, i.e. use 192.168.0.x on modem 192.168.2.x on router. Do both default to 1.x?

    Double nat should basically work, but does need dmz from modem for incoming, ddns needs to be setup to lookup the real external ip etc
