SoftEther VPN User Forum

Good afternoon! I'm trying to solve a very simple task - establish PC-to-PC VPN connection. One computer (Windows 8, behind the router) is assumed to be a server. Another (Windows 8.1, behind the router) is a client. I have installed the VPN server (Ver 4.29, Build 9680) on the first PC, and the VPN client (Ver 4.29, Build 9680) - on the second. I used DDNS hostname. The problem is that a connection to the server could not be established (Error Code 1). Then I've installed the VPN client on the first PC too. From that client the connection is easily established! Could anybody help me with the matter?

Can you ping from the second PC to the global IP address of first PC side?

Yes, pings seem to be OK.
