I have another Sonicwall PRO 1260 Enhanced that I am having issues with all of a sudden. Out of all the firewalls that I manage Sonicwalls are the only ones that give me heartaches.
Starting on Friday, afternoon TCP Connections coming from he outside are being dropped. Nothing has really been changed to my knownledge. This account I have just taken over and I can't seem to figure out where this has gone wrong. I was notified when the End Users could no long remote in via SBS Remote Workplace. I went and did the normal and checked the server, and even rebooted the server. Still nothing, so I checked the firewall and looked at the logs and discovered all WAN TCP Connections are being dropped.
Now I created a backup of the device which is by habit of all firewalls I managed, and when I tried to restore the device Settings I am getting a "Error: Configurations Settings files is Corrupted" which is a firs for me.
Whats going on or what am I missing? Why would all Incoming WAN TCP Connections be dropped?
