is a mac address case sensitive
MAC Address Case Sensitivity. I'm trying to connect Macintosh Power Book with OS X+ and three WinXP machines to internet through my SMC7004VBR router and Surfboard SB4100 modem. The MAC addresses of all four machines have been entered into the firewall set up.2) does not allow the Macintosh computer whose Ethernet address includes a lower case d access to the WAN, and (3) the Macintosh computer is not listed by WinXP as a Workgroup computer. Special care has been exercised to not confuse the number zero and the letter oh when entering the MAC/Ethernet address.
