    It just displays the router's mac id there. It doesn't allow me to change it..

    Umm... Yes it does. Under "WAN Port" enter the MAC address you so desire, and click SAVE at the bottom of the page :p

    What's the difference between that WAN mac id and the router's mac id listed on the same page?

    I think the address shown is the LAN MAC address.

    The order is LAN/WAN/Wireless. For example:

    00:0F:66:01:02:BB LAN
    00:0F:66:01:02:BC WAN Port
    00:0F:66:01:02:BD Wireless Interface

    This can be changed, but not from the GUI. You'd have to telnet in and change some of the nvram settings.

    The WAN Mac ID is the MAC address that your cable/DSL modem, and the outside world can see. If your ISP requires you to register a MAC address, it's the WAN mac address of your router that you would give them. This can easily be changed in case you're just getting your router and your ISP already has a specific network card bound to your ISP account already... In that case, you can simply "clone" your network card's mac address to make it appear that the router has now become that NIC, thus fooling your ISP.

    As for changing the MAC address off the router itself, or the LAN mac address there's really isn't any point to doing this. I don't see any reason why this would be necessary. You router's MAC should never match a NIC's by mistake, because they have a separate string for routers, and it also goes by brand. Meaning if you have a Linksys router and a Netgear NIC, the Netgear NIC will NEVER accidently match the MAC of a non-Netgear product.
