I'm not quite sure the reason fpr the static IP addresses here, although different routers deal with this in different ways. You might want to spell out your understanding of what your router does in this area. As for MAC addresses, this will stop accidental access but will not even slow down a hard core hacker. The MAC can be spoofed, and if you are depending on it for security you may suffer the loss of a lot more than a little bandwidth. The proper approach for wireless security is to use WPA encryption (and absolutely not use WEP) with a long non-guessable, safe from dictionary attack key. If you do this you are secure, if you don't you are not. And even without using MAC spoofing a hacker may find it more useful to just passively monitor your wireless traffic and steal things like e-mail addresses and passwords (which often lead to other saved accounts and passwords, as well as bank accounts and more) than bothering to steal bandwidth. If you feel better about using a MAC table after setting up WPA, that's fine although it really isn't needed. But depending on a MAC table for any form of security is idiotic.
