It's been such a strange trip dealing with Comcast tech support. One guy will say the firewall's on, another says it's off. Nobody can tell me what mac address they see on an interface.
Anyhow - what I want to do in the future for these baby branch offices is to get onto the cable modem from afar. They told me on the call that I could manage the device at a 10.x.x.x and a standard uid/password. What interface on the cable modem would give me this access? I have a Cisco ISR on the inside of the cable modem with a public IP address. Would that interface be dual addressed with the 10.x.x.x management as well?
Then the big question - if I wanted to login to the cable modem from my data center public NAT IP, should I be able to do so if someone configures that permission locally? I just want to see the settings with my own eyes and without having to wait on hold 15 minutes for a barely helpful Comcast tech.
