Yes, you're write. I called them to confirm the issue and I provided my MAC address so they will research and see if it's allowed according to their policy.
There's one more question, if you don't mind: I am able to change the MAC address of my Ethernet interface, using the "mac-address" command through IOS. But the same command is not available to the cable-modem interface. I'm not sure if it is not allowed at all or if it's a limitation of my IOS version. Do you know if it's possible to manually set up a MAC address on the cable-modem interface? Thank you!!
