Question:
I set Up L2TP over IPSec VPN with Nebula Cloud Authentication and L2TP VPN client is established successfully. Why is the L2TP VPN client disconnected approximately in 30 minutes?

Answer:
It may be related to the reauthentication setting. You can go to Monitor > Firewall > Event log and check if the log "re-auth timeout" appears.

Then go to Configure > Site settings > Captive portal reauthentication and check if the setting of "For cloud authentication users" is modified manually. The default value is "Every day".
