If I have enabled MAC address filtering (not to be confused with "Macintosh") on my network router, does it help to whitelist all of the MAC addresses on my network (i.e., of my printer server, Xbox, iBook. and G4 tower)? Or is it sufficient to do this only for the two "real" computers?

Also, related question (sort of): Does it pay to enter the DNS server addresses I'm using into the router as well as the client machines?

If your network is managed by a wireless router, you may only have one MAC address whitelist. In that case, go ahead and add EVERYTHING that has an IP address, because it will be excluded unless you add it.

If you have an access point separate from your router, then you should only need to add the equipment that connects wirelessly-in the access point's whitelist, of course.

If your computers are running with automatic IP addresses (using DHCP) then they'll get the correct DNS server addresses along with everything else with their IPs all passed on by the router. You may have to enter that information in the router, but using DSL from SBC, I've never had to do that-it gets that from the ISP along with its own WAN IP.
