Adding to Pascals comments,
1. Check that the "Hosts" Public IP address is the correct one placed in the "Joiners" server name... So on the VPN Host machine, go to
http://www.whatismyip.com ... and then confirm that that same address is placed in the VPN Joiner (client), as shown in image below.
2. To telnet into the Host:
On the "Joiner" (client), open a command prompt and test via telnet whether the ports are opened correctly on the "Host".
(windows) Start menu --> Run --> cmd --> telnet -->
open vpn.myserver.com 809
If the Windows goes blank, or just says "Press any key" then you have connectivity to that port.
If you get the error message: Connecting To vpn.myserver.com...Could not open connection to the host, on port 809: Connect failed
... Then there most probably is a firewall blocking the port....
