24.1 Legacy Series / Re: IPv6 connectivity loss on 24.1.10

I live in Sweden and the ISP is Bahnhof.. I talked to them today and they have no issues. I am also going to talk to my layer 2 provider, they have had issues with delivering v6 before..

Ok, can I debug in more detail?

If I change Prefix Delegation Size to "None" instead of 56, then I get back my v6-address on the WAN interface. But the tracking doesn't work. If I change back to 56, then the "status-code UnspecFail" show up again.

This has been working for several years, I'm not sure what to ask my ISP?

My IPv6 is also broken since a few weeks back.

I get this when tcpdumping:

Code: [Select]

# tcpdump -ve -i pflog0 udp port 546 or udp port 547

08:47:53.564963 rule 91/0(match): pass in on igb0: (class 0xe0, hlim 128, next-header UDP (17) payload length: 179) fe80::2022:ff:fe01:1.dhcpv6-server > fe80::2e0:67ff:fe2c:f570.dhcpv6-client: [udp sum ok] dhcp6 advertise (xid=7206b (IA_NA IAID:0 T1:3600 T2:7200 (IA_ADDR 2001:9b0:130:0:ffff:cd9e:c6ea:d722 pltime:54000 vltime:86400)) (IA_PD IAID:0 T1:3600 T2:7200 (IA_PD-prefix 2001:9b1:23ff:6800::/56 pltime:54000 vltime:86400)) (client-ID hwaddr/time type 1 time 700187364 00e0672cf570) (server-ID hwaddr/time type 1 time 660837239 00505687fc2c) (DNS-server 2001:9b0::53:1 2001:9b0::53:2) (status-code UnspecFail))

The last part, (status-code UnspecFail), doesn't look good.

I have tried all tips in this thread, patching back and forth, reverting to 24.1.8 and 24.1.9, nothing helps. Should I revert even further?

One of the patches doesn't seem to work anyway:

Code: [Select]

# opnsense-patch e94baab85

Found local copy of e94baab85, skipping fetch.
1 out of 1 hunks failed while patching etc/inc/filter.lib.inc
From my ISP i get DHCP6-PD with a /56.
