[Swan] Configuring L2TP client using NetworkManager

[Josh]

Hello Paul,

You are correct. I found instructions from a random VPN provider:

https://www.rapidvpn.com/setup-vpn-l2tp-ubuntu
https://www.rapidvpn.com/setup-vpn-l2tp-fedora

Ubuntu 20 uses strongswan for l2tp/ipsec and connects to keenetic l2tp 
server just fine.
Fedora 36 uses libreswan and connection to the same instance fails with 
error messages matching

Could anyone suggest any debugging steps?

Josh.
