SG-1000 Lost WAN Access
-
We have an SG-1000 deployed in at a remote satellite office. This morning the two person office lost all WAN connectivity. Other than IPSec to the main office, DHCP, DNS, there are no other major services running on the SG-1000.
We confirmed with the internet provider that everything was good on their end. Able to remotely reboot the modem, and still didn't have internet access.
The ultimate resolution was a manual power cycle of the SG-1000.
Now I'm trying to discover what may have gone wrong. Here are the log entries surrounding the time in which we went down:
