Hallo everybody!
Is it possible to use L2TP-site-2-site-vpn with Astaro v7.5? I know there is an IPSEC-option in Astaro-site-2-site-VPN but is this something like L2TP-over-IPSEC?
I guess that you want to connect a home Astaro to one of those VPN services, and that's not possible with L2TP. It is easy with pure IPsec, and others have written here that it's possible with some knowledge with the SSL VPN.
L2TP in Astaro is only a server, never a client.
