IPv6 Settings: 6rd Tunnel
6rd Prefix: 2602:240::/28
IPv4 Border Router Address 188.8.131.52
IPv4 Common Prefix Mask: 0
IPv6 DNS servers are the Google ones (2001:4860:4860::8888 and 8844) although I've tried with blank too.
Delegated IPv6 Networks are blank.
Public IPv4 is 184.108.40.206/24 (static)
The router gets an IPv6 address of 2602:24a:de45:b5e0::1/60.
Am I missing anything obvious? Anything else I should try?
If I pop Sonic out and plug in Comcast with auto settings, it works, so my PC seems to be happy with IPv6.
