RADVD and IPv6 Killed by Modem Reboot

eri--

From what i see you do not have the use v4 link for v6 connectivity toggle on this WAN.
That would make sure it works as needed on such renewals.

Sorry. Didn't realize this was a toggle. I can try again and post the results. Only, where do I find this toggle?

It's in the interface settings for the WAN interface.

I tried the "Use IPv4 connectivity as parent interface" again which is the only thing that sounds correct.

Same results where IPv6 connectivity doesn't work with that setting.

When I uncheck that setting, I get IPv6 connectivity back. Am I missing something/doing something incorrectly?

Razzfazz, are you having luck with this?

I haven't tested unplugging my upstream yet, but IPv6 seems to work for me with that checkbox enabled.

Interesting. I'm getting some new hardware so I'll test a clean install of pfsense soon. Meanwhile, the following is the logs relating to turning on the "Use IPv4 connectivity as parent interface" option.

BTW, I tested the "Use IPv4 connectivity as parent interface" option. I was able to retain IPv6 connectivity. The only issue I had with it is that enabling it seemed to require a reboot. Aside from that, so far so good!

Thanks a lot for this fix. :) :) :)
