I have 2 big problem in a cluster Active/Passive configuration with two MAG4610:
1) SSL-VPN connection constantly disconnects automatically every 50 to 60 minutes;
2) Some users are also experiencing no response from SSLVPN after connecting.
For these problem, I would update the firmware on the newer version (major that I can install is 8.3R7.0)
1) The upgrade from 8.2R7.1 to 8.3R7.0 can have problem with end users (Es. change version of installer component for the SSL-VPN);
