Connecting to WRT54GS but not to the internet

    Hello everyone.

    I have the WRT54GS up and running and I use it as a gateway for my internet connection with my DSL modem hooked up there.
    However recently a friend living next door bought a wireless PCI card and wants to connect to my AP.
    Is it possible to give this computer an IP which will not be able to access my Internet connection but connect in the internal LAN? How can this be done?

    It would depend on how technically aware your friend might be.

    One way, would be to change the "Default Gateway" IP address on your router, where it services DHCP requests for your LAN, to a non-valid address. When your friend tried to surf the internet (or anyone else trying to get a 'free ride'), his network card would not know the correct address for your router (gateway device). To make it more obscure change the router's default LAN address from (which can be easily guessed), to something like Like I said, if he/she is technically savvy, then he could probably figure it out eventually.

    In addition, if you go this route, you will need to change your own network connection to a static (fixed) IP address, along with the correct ( default gateway, or else you won't get internet access either.

    Have fun...
