Ipsec errors for multi office vpn
-
Hi all
strange issue that I am having. I have a multi site setup with multiple vpn tunnels between them.
Problem is that 2 tunnels at each end are showing they are working. but they are not. ( they have worked prior to today )
I get these errors a lot in the logs and wondered If anyone could shed some light or point me in the right direction
