For several years, I had Comcast IPv6 working with my UTM 9 Home software (currently running 9.510-5). About a year ago, IPv6 suddenly quit working, and I haven't been able to make it work ever since. So I turned off the IPv6 option and tried to ignore it, but I'd really like to get this working again. I've spent several hours with it today, and I think I have everything configured correctly, and the UTM gets an IPv6 address, but I can't get a delegated prefix. Here's what I see in the IPv6 status window:
Note that the Delegated Prefix line isn't even there. Here's what my WAN interface looks like:
I will note that if I bypass the UTM and plug a computer directly into the cable modem, IPv6 works just fine on that computer, so clearly the modem (a Motorola MB8600) is capable. Am I missing something in the UTM configuration, or do I have another problem?
