⚠ Any errors using L2TP / IPsec VPN?

❶ Username, password and pre-shared key are all “vpn” (3-letters). Especially, make sure you input the pre-shared key correctly.

❷ Android & Mac OS X needs a special setting to make the VPN server relays all traffics. Confirm the above instructions again.

❸ Make sure that the destination hostname or IP address are correct, viewing the VPN Servers List page.

❹ In some countries or regions, specifying DDNS Hostname (.opengw.net) might fail. In such an environment, specify the IP address directly instead of DDNS hostname.

❺ Your local firewall might filter any L2TP / IPsec packets. In such a network, L2TP cannot be used. If you use Windows, try Using SoftEther VPN Client. Mac, iOS or Android, try Using OpenVPN.
