IPSec tunnel has gone down im at a loss
We have 2 locations each with a pfsense box with a IPSec vpn between the 2 that had gone down in the evening
pfsense version 1.2.3 at both locations and no changes have been made in months
the main location packet capture shows only out going messages to the public IP and vice versa
im not sure where to look now
resolved the issue, Verizon had changed our public IP address at midnight without warning or reason.
