random ipsec/l2tp disconnects and unable to reconnect
-
As per the netgate docs, I have set up a mobile IPSec/L2TP VPN server with radius/nps authentication and it works, but hasn't been very reliable. I have about 30 remote users and some users have random disconnects during the day and need to reconnect. For the most part I had chalked it up to users crappy home internet breaking tunnels. Other times (like today) multiple users get disconnected around the same time and nobody is able to reconnect. Slowly more users disconnect and cannot reestablish a connection. While they are reconnecting I can see the user show up briefly in the ipsec status list but it disappears after a few seconds.
Sadly, rebooting the box fixes the issue for a while.
Can someone point me to what I should be looking for in the logs? Any guidance is appreciated
