History

#1 Updated by Chris Palmer about 1 month ago

Just want to confirm that this appears to have kept my box from booting. But would restart over and over. No logs to share.
Once I deleted 6to4 from my WAN the box started just fine. Watchguard XTM5 box.

Thanks, i can no longer reproduce the panic.

If 6to4 itself works properly now i cant tell, i have not used it before..
If i configure ipv4 with: 12.13.14.15 i do see it has a v6 ip: 2002:c0d:e0f:: looks okay to me.. And surly better than the crash that happened before ;) .

Anyhow this ticked can be closed imho. Thanks again.

#5 Updated by Chris Palmer 26 days ago

Confirmed working here as well. Thank You!

#6 Updated by Chris Palmer 26 days ago

Seems right now I cannot monitor the gateway though if I ping from diagnostics the ping returns fine.

Gateway monitor shows unreachable.

2002:c058:6301::1

Not sure if related.

#7 Updated by Chris Palmer 26 days ago

Actually just shows "Pending".

Other (2.3) box works.

Yeah, that's a different issue, can you open a new ticket for it ?
