[strongSwan] IPSec+L2TP connection randomly drops

It's certainly not something with strongSwan. Maybe Windows tries to access some URL to check connectivity, like Android and iOS do.

And the connection dropped on both clients I was testing, simultaneously, and that makes me think there is something wrong with the VPN server, not clients. Also L2TP IPSec connection works without interruption from the same clients when connecting to a Mikrotik.

>>> I successfully configured strongswan + xl2tpd and it works but connection is randomly dropped and not re-established. 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.
