I'm trying to configure my Verizon firewall, which is MAC address authenticating, to allow a new machine. It's an older Windows Vista machine, and I obtain the MAC via IPCONFIG /ALL. I take the MAC's I see there and try to enter them into the Firewall config section of the router config, and it says "Invalid MAC Address" ? What's going on here?!
BTW, I already have about 8 machines configured and working just fine.

While I see you solved your issue, there is a (or are) problem(s) to be aware of.
#1 MAC Address(es) are always sent in clear regarless if the type of encryption.
#2 Since it is possible to spoof/clone a MAC Address on a router (for example as shown at http://ui.linksys.com/files/E4200/2.0.25/wanmac.html ) it is also possible to spoof/clone the MAC Address on a computer.
#3 If someone does not know how to spoof/clone the MAC Address on their computer if you do not use wireless encryption (WEP, WPA, WPA2) to protect your wireless network, that someone can still see your traffic.
