    I'm using a WRT54G-DE Router ans I am searching for a firmware that allows me to
    - deny all Computers in the LAN to use the internet
    - makes it possible that listet Computers (MAC-adresses) CAN use the internet

    Is there a firmware that can do this?

    Thank you for your answers!

    I think parental controls could do this relatively easily, with HyperWRT Tofu or Thibor at least.


    1. Use static DHCP to assign IP addresses to the MAC addresses you want, and
    2. set up a DHCP range away from those addresses for all other clients, then
    3. put those specific IP addresses as the only ones allowed in parental controls. Block all others from Internet access.

    Without Tofu or Thibor, I would suggest turning off DHCP entirely, and having your computers set up with static IP addresses, then setting up the IP addresses in Parental Controls.

    There are probably far more advanced ways to do this in startup scripts, in DD-WRT, etc. But this one is relatively simple. Not foolproof, mind you - someone could still mess with an IP address or for that matter spoof a MAC address, but it's decent.

    NateHoy's suggestion will work fine but I figured I should point out that even the stock Linksys firmware includes support for specifying MAC addresses for the Access Restrictions feature.
