22.7 Legacy Series / Re: IPv6 Issues with 22.7_4

Nice! Thanks for the effort, Franco

Maurice's suggestion seems to helped too. I left a ping running after disabling "Use IPv4 connectivity" for the problematic WAN interface.

ping 2001:4860:4860::8888 | while read l; do echo `date` $l; done
Mon Aug 15 06:26:37 PM CEST 2022 64 bytes from 2001:4860:4860::8888: icmp_seq=1 ttl=120 time=9.63 ms

I haven't lost IPv6 since, it's still going strong ...

EDIT: next day, still stable

Weird, I probably had "Use IPv4 connectivity" enabled since I setup this install a couple of years ago.

Cheers, Franco. Output sent via PM.

No custom patching, one interface to my ISP's NT, IPv4 DHCP, IPv6 DHCPv6 and "Use IPv4 connectivity".

Just a wild guess: "Use IPv4 connectivity" is only meant for PPP, which you don't seem to use. Any improvement if you disable this?

Cheers

Cheers, I disabled it. Gateway came up, but I doubt this will stick.

I looked at the log, after the change and once again saw:

2022-08-15T18:20:15   1   Error   opnsense   90129   /usr/local/etc/rc.newwanipv6: The command '/sbin/route add -host -'inet6' '2001:4860:4860::8888' '<my-ipv6-gw>%'' returned exit code '71', the output was 'route: <my-ipv6-gw>%: Name does not resolve'

It seems that one of the provisioning steps either needlessly leaves the % or fails to add the interface string, because rc.newwanipv6 adds this to the log just a second later:

I tried to review this a bit, but quickly reached my skill ceiling. I can edit the files and test, but I definitely need help with the script trouble shooting.

Would you mind sending this to me privately for inspection? Just that "The command '/sbin/route add -host [...]" line. Maybe a stray character in there or something else I'm missing, but impossible to decide on next step without it.

Thanks for the initiative. I sent you a PM with the details.

So what's 'xxxx' here. It is supposed to be a gateway but looks like a FQDN?

For dslite, do you use any custom patching?

I sanitized the log output. It's the public address of my IPv6 gateway, which I string replaced with xxxx.

No custom patching, one interface to my ISP's NT, IPv4 DHCP, IPv6 DHCPv6 and "Use IPv4 connectivity".

22.7 Legacy Series / IPv6 Issues with 22.7_4

« on: August 15, 2022, 02:33:10 pm »

After three years of pretty much flawless operation I encountered an issue I'm not able to solve myself.

Since my upgrade to 22.7 I keep losing IPv6, intermittently.

Service is dslite, upon release/reload of the interface, manually restarting dhcpd6, IPv6 is working fine, but after a while it stops

start:
Mon Aug 15 12:47:48 PM CEST 2022 64 bytes from 2001:4860:4860::8888: icmp_seq=1 ttl=120 time=9.35 ms
stop:
Mon Aug 15 01:44:10 PM CEST 2022 64 bytes from 2001:4860:4860::8888: icmp_seq=3280 ttl=120 time=7.74 ms

These are the events I see in the log at the given time:

It's a multi-wan setup with dpinger for gateway monitoring.

This behavior is really strange. Any pointers or assistance would be most appreciated.
