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.
