    i used to be able to do this in dd-wrt, release or renew the dhcp lease from my isp, and i would get a new ip address. i've looked through all the menu options in tomato and can't seem to find this functionality. i realize my new isp may just give me the same ip, but i can't even find the option on the web interface. i'd settle for a command line incantation i could execute through ssh.

    i have att dsl and had to put the dsl modem into bridge mode with the linksys (gl) running ppoe (tech support said that was only way it would work with the router, but i find that hard to believe).

    Right on the main page, there is a Disconnect and a Connect button. You can script it as well.

    Of course you would want the DSL modem in bridge mode to avoid double-NAT. DO you see a problem with that?

    doh, those buttons need to look more like buttons :)

    no, i just seem to recall that i was able to do this before (a couple of years ago) with the ppoe on the dsl modem. could just be my bad memory.

    In my case, my ISP will give me a new IP addy if I change the MAC address that connects to teh modem. if I connect a computer directly to the modem I get one IP and if I connect the router I get yet another IP..

    Same here. I have had the same DHCP IP address since I have had Comcast. Change the MAC and the IP follows.
