Right… well, I had ipv6 working fine before requesting a static v4.

I’ve just re-enabled v6 and now at least my router appears to be talking to a dhcp6 server — so that’s new!  It didn’t get any reply at all after I initially went static v4.

However, the v6 client gives up with:

Code: [Select]
advertise contains no address/prefix
Will have another tinker tomorrow!

Could you do a release / renew on your WAN and let us know if that pulls a prefix?

No joy after a release/renew unfortunately!

Does sound like OPNsense is misbehaving according to skyeci.

Here’s some longer log output, in case it’s any help.

I have dhcp6c set to only request a prefix with a 56 prefix delegation size.

Code: [Select]

Interesting, are you also selecting "only request prefix"? Or something to that effect

I am indeed choosing “only request prefix”.  Should that be off?

Nope that should be on, along with send prefix hint.

Everything else should be default

Gave it a reboot and I think I’m in business.  Thanks for your help!

I’ll keep an eye on it, given others have had problems with v6 in OPNsense.

So, after a few days I did start getting weird things happening — slow page loading, images failing to load, that sort of thing.  Turning off v6 solved the problem instantly.

Not sure if that’s a sign of OPNsense losing the prefix — everything looked fine on the dashboard.

But I’ve upgraded to the latest OPNsense and it’s been fine for a few days.  If the problem repeats, I’ll turn off IPv6 until OPN sort out the issue — will raise a bug with them after collecting all the diagnostic info I can.

Just for info, since the last post I've had no IPv6 issues at all.  OPNsense has been up continuously (apart from updates) and there's been no IPv6 oddness.

My config, for reference:

  • OPNsense 23.7.11-amd64
  • WAN IPv6 Configuration Type: DHCPv6
  • Request only an IPv6 Prefix: enabled
  • Prefix delegation size: 56
  • Send IPv6 prefix hint: disabled
  • Use IPv4 connectivity: disabled
