SoftEther VPN in China can not connect

Post by SyouTe » Sat Nov 18, 2017 2:10 pm

Such as the title, VPN in China has been severely blocked by the firewall, I do not know how to use, suggesting: protocol errors and other issues, I hope you get the help, thank you.

Did you stop the VPN server from listening on all ports except tcp 443? disable everything but softether protocol... disable openvpn, disable l2tp/ipsec/ disable udp acceleration, disable dynamic dns server, disable ms-sstp, disable azure, disable everything....

If your using a remote VPS to host SoftEther VPN server, make sure to close port 80 on the server with iptables...

Assuming you don't have a default INPUT drop policy....

Code: Select all

# Drop all incoming traffic on port 80
iptables -A INPUT -p tcp --dport 80 -j DROP
Then you are also going to have to disable IPv6 on the client's host... Also make sure that DNS requests are sent through the VPN tunnel. And disable webRTC and Flash.
