After a year of everything working fine, I'm suddenly getting tons of "IPSEC Replay Detected" entries in my Sonicwall log (Standard OS) from the Global VPN clients that are connected. Firmware is184.108.40.206-95s on the 2040 (the one at the main office) and all the Global VPN clients are the latest ones.
Also, I'm getting quite a few Probable (AND Possible) Port Scans, and the ports being scanned are usually the scratch ports (8,000 upwards to 56,000).
It looks like some people around the net are having the same problem as I but no one seems to have a solution. Does anyone know what can be done to fix this?
