📄 Description

I think this should help with keeping VPN connected when the client is idle. From libreswan doc:

nat-keepalive
whether to send any NAT-T keep-alives. These one byte packets are send to prevent the NAT router from closing its port when there is not enough traffic on the IPsec connection. Acceptable values are: yes (the default) and no.
