History

#1 Updated by Chris Palmer 10 months 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 10 months ago

Confirmed working here as well. Thank You!

#6 Updated by Chris Palmer 10 months 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 10 months ago

Actually just shows "Pending".

Other (2.3) box works.

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

Thanks!
