OpenBSD FAQ: Virtual Private Networks (VPN)
Host to host VPN with PSK - Libreswan Generate a pre shared key (PSK) for use in this VPN. PSK is really not a password, it's a key and you must make absolutely sure it is transferred to remote end in a secure way by using PGP/GPG or ssh. Secure PSK should be at least 32 characters random but 64 chars is better. We can actually cope with even longer PSK sizes but not all What is a pre-shared key or shared secret?

IPsec VPN Overview - TechLibrary - Juniper Networks
In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used.. Key. To build a key from shared secret, the key derivation function is typically used.
Select Use pre-shared key for authentication. In the Key text box, type the pre-shared key for this tunnel. The pre-shared key must match the pre-shared key configured on the Firebox Mobile VPN with L2TP IPSec settings. If Mobile VPN with L2TP on the Firebox is configured to use a certificate as the IPSec credential method:
In Ubuntu 18.10, I'm trying to set-up a L2TP VPN connection with a WatchGuard server using PSK with SHA1-AES 256bit DH group 2 for Phase 1 and ESP-AES-SHA1 group 1 for Phase 2. I tried with both Strongswan and Libreswan but always get a NO_PROPOSAL_CHOSEN error, no matter which algorithms I choose in ipsec.conf or in GNOME network manager.
