I have multiple RV082 v3 units running fw 4.1.1.01 and 4.2.1.02 for 1-2 years without major problems.
I put new FW 4.2.2.08 on one unit (big luck only one , you will se why) and I noticed that VPN tunnels does not permit traffic when using backup IP - at the other end of VPN tunnels (96 per RV082) I am using a RV042G unit with fw 4.1.1.01 or 4.2.1.02. Each unit has 2 different ISP, so I am using Primary IP and Backup IP . When remote unit lost main ISP , VPN tunnel show connected using BACKUP IP but no traffic allowed. Sometime if I EDIT tunnel on RV082 and save with no change traffic is allowed ,but only sometimes.
So I have to get back to 4.2.1.02 on RV082 and here comes the ugly thing: unit got factory default after fw update (automatically, no info about) and configuration saved from unit running fw 4.2.2.08 couldn't be restored (no info, just browser reset to login and no changes ) and i had to input all 96 tunnels again .
Anybody noticed this behavior?
