Snaggin the public IP through a WRT54G

    Is there any way to get my WRT54G to let me get the public IP address assigned to me by my ISP? Essentially, this is an IP passthrough but I have found no support for it.

    So far, the only way I've been able to accomplish this is to take the router out of the equation by connecting a long cable to my modem. A cable kinda defeats the purpose of having a wireless router.

    turn off DHCP on the router and plug your isp's modem into one for the 4 lan ports instead of the wan/internet port, and the first machine to turn on will get the ip.

    That's the best solution I've heard and sounds absolutely do-able.

    Maybe someone could include a pass through feature in an upcoming firmware release?

    that would completely defeat the purpose of having a router if all the ports are bridged...

    Believe it or not, there are times when this setup is useful. I want to do it so I can play Command and Conquer: Zero Hour using direct connect. This option does not work through a modem, regardless of how may ports you open.

    The only thing missing in your solution was to reboot the modem so it will release the MAC address of the router and pick up the MAC of my machine. After I realized that, I was able to get the address.

    Once DHCP is disabled, the only way to get back to the router is to reset it. Is this a harmful practice if done too much?

    well it's still not a router if you bridge all the interfaces thats why ou just plug it into the lan port... you can bridge it via telnet in any of the firmwares if you really want, and I think sveasofts latest thing lets you select what vlan you want each port to belong to.
    and yes you need to reboot the modem, I forgot to mention that .. I wouldn't recomend resetting the to factory defaults all the time you may end up wearing out the flash (eventually after a long long time) if you statically assign an IP to your computer you should still be able to login to the router, as long as your on the same subnet

    I'm not sure how setting a static IP would let me access the router's config. By creating a bridge, isn't it just invisible like a wireless switch?

    The subnet I'm getting is the same as the router.

    you have to be on the same network as the router, the router can see a computer on any of the ports on the back of it so it will be able to talk to you, your isp will assign your computer a public ip, so you'll need to statically configure a private ip on your network card on the same network as your router, if your router is 192.168.1.1 then you can set your ip to 192.168.1.2 and you should be able to log into it then.
