Thank You Again all for your ideas & education. I'm learning quite a bit, with even more to learn. This is an interesting topic to me.
QUOTE: There should be a label on the back of the modem, however, that will list at least ONE of the above MAC addresses (probably not the Alien one). If you haven't checked already, that's an easy step.
I checked the label on the modem, Ember1205, and the address 5c:8f:e0:e7:61:is there three times, each with a different last two characters.
One titled CM MAC ends with BD. As far as my research could tell me, the "CM" means it is a cable modem.
The next on the label ends in BE and is titled E-MTA. The only information I found on E-MTA was from another ISP's help pages which stated it is for phone or television. Since my television system tees off ahead of the modem, I am guessing it is for telephone.
The third on the label ends in BF and is called WAN MAC. My guess? It is the WAN address the modem uses to communicate with the ISP. (A large guess on my part)
The one part that still makes me a bit uneasy is that Port 23 (telnet) is open and there is no place to close it. Pings are not showing as returned, so maybe it is not a problem.
