Hi all,
I hope you can help me with my Strongswan Configuration. The goal is to
have a VPN Server for my Smartphone (Android) and my Computer (Ubuntu)
in America. (I am from Germany)
The problem is that I can't connect to the server. Because of this
syslog (Server) message I think thats a problem with the configuration.
