I find when troubleshooting VPN problems I have a difficult time trying to understand what the event log is telling me in some cases. I have seen allot of error codes that I have know idea what they mean and there is also the famous "tunnel to peer closed, reason: None" . I would like to get "smarter" in understanding this event log and the various events and error codes but I have not found a "how to interpret VPN error codes guide" Is there any reference at all out there ??? Thanks for responding.
