[strongSwan] IPSec+L2TP connection randomly drops

Hi,
As you can see for yourself, the initiator deletes the CHILD_SA in every case. Windows 10's VPN implementation was broken a lot of times in the past, so I wouldn't be surprised if they did not implement inactivity timers
and reestablishment correctly. AFAIK the Windows 10 VPN implementation does not try to keep the CHILD_SA up at all times and you can't change that.
Kind regards
Noel

I need the tunnel to be permanently established, with no inactivity timeouts and such stuff. Once it was dropped after (roughly) 9 hours of inactivity, second time after a few hours of inactivity, and last time after half an hour of inactivity (this last time I tested it with 2 clients and both got disconnected at the same time so I guess the problem is somewhere on the server). Clients are Windows 10 machines and are behind NAT. Server is not behind NAT and has a public IP, no firewall. I am using a pre-shared key with mschapv2, no certificates. On server, all software is latest versions.

The 158.193.0.0/16 is just a network I was testing split tunnelling which didn't work but I don't think it has anything to do with the connections being dropped. Server is configured to hand out IPs in range 172.27.27.2 - 254, IP 172.27.27.1 should be the server (or gateway) itself.
