gif0 does not come up after reboot

vex

@stephenw10 I managed to create a second gif while the first one was still down. Setting the parent interface to WAN worked this way.

2022-10-21 17 38 18.png
Unfortunately, the interface still doesn't come up during boot and even more unfortunate is that the IPv4 routing does not work if I use WAN as parent interface. It shows as up, but the tunnel does not work.

dmesg shows

Don't know where to find logs of gif creation at boot time.

stephenw10

If you have just rebooted it should be in the main system log when it tries to bring up the tunnel.

Does that new tunnel come up if you restart after booting? Despite having no routable IPv6 address on WAN?

Do the PPP logs look like it's trying to pass a v6 IP to the WAN as well as a prefix?

4IN6 (gif0) tunnel does not come up with the reboot. If I now manually do the "Save"/"Apply changes"-Wizardry, the gif0 comes up and the logs show:

What I find slightly interesting, is that the IPv4 tunnel gateway has 100% packet loss in the gateway monitor, although it works flawlessly.

Kind regards

@vex said in gif0 does not come up after reboot:

Oct 22 20:19:13 php 458 rc.bootup: The command '/sbin/ifconfig 'gif0' description '4IN6'' returned exit code '1', the output was 'ifconfig: interface gif0 does not exist'
Oct 22 20:19:13 kernel vtnet0: link state changed to UP

That's with the gif tunnel using WAN as the parent? Or LAN still?

Is the PPPoE interface first in the list?

I note that you appear to have WAN set to dhcpv6 but the PPPoE is passing an IPv6 address via IPV6CP directly.

The IPv4 gateway may simply not respond to ping. Try setting a monitoring IP somewhere further upstream like 8.8.8.8.

That's with the gif0 using LAN as parent. PPPoE is first in list, yes.

So instead of using DHCPv6 as configuration type, should I use something else there?

Yeah, I switched to monitoring the IPv6 CG-NAT/AFTR address.

This is the complete log of booting with gif0 and WAN as parent:

Thanks again for having a look into this.

stephenw10

Hmm. Even with that don't see it trying to restart the gif tunnel (even if it would fail) after the WAN connects and gets a new IPv6 address and I would expect it to trigger that.
It could be because it's link-local only and that is not seen as a valid address. Though it is valid for a transport link and that's common on WAN. Or potentially it comes up at boot and somethings are suppressed during boot to prevent flapping.

However what you're seeing is exactly this: https://redmine.pfsense.org/issues/8273

Which should be fixed by this: https://redmine.pfsense.org/issues/6507
But that is in 2.6.

Does manually running /etc/rc.newwanipv6 lan after boot bring the gif tunnel up? What is logged when you do that?

Ok, interesting. So after running some tests here it appears that never gets called because it's not actually a WAN. I've asked internally because it's not clear to me what should happen there currently. As far as I can see it only restarts DNS and DHCPv6 on the tracking interface.

@stephenw10 Just an hypothetical question: Would this bug be fixed if I paid for one of your support contracts and opened a case?

No. Support contracts are not paid development so it would make no difference here.

There are large number of moving parts currently and development time is at minimum. I didn't see much of a response previosuly. Let me retry....
