radvd needs restarting after a reboot

[Ozymandias]

After every reboot I need to restart radvd in order to get an IPv6 address on my windows machine.

Which version would that be?

2.19_2

OPNsense, not radvd. ;)

[Ozymandias]

Sorry 23.7

[franco]

To be honest it should have been fixed with https://github.com/opnsense/core/issues/6637 in time for 23.7 and I got multiple confirms.

The full log would likely help. I suspect PPPoE flapping quite a bit...

I've sent the log via private message

Hmm, so several seconds after saying IPv6 is up your setup doesn't find an IPv6 and also does not acquire one during boot sequence which makes me think the final connectivity is set up later when all the scripts looking for it ended. Not sure what to do here, but it's not a locking issue anymore.

You could try to increase the DAD timer via

# sysctl net.inet6.ip6.dad_count=10

and see if that makes it better, but 10 seconds is just a guess here... it could also be minutes...

OK I'll try that a little later tonight and let you know the outcome.

net.inet6.ip6.dad_count = 10 made no difference.

I tried up to 60 with no positive result  :(
