Hi: For the benefit of those who are in/or travelling in China, some clarification on VPN usage in general, that may also help you with your use of your GLI Router there. By way of introduction, my business is computer security, and I have employees who travel to China regularly.

@alzhao, you are correct that OpenVPN is generally blocked in China. Standard OpenVPN will get blocked by algorithmic filters in Great Firewall. However, some VPN Providers (ExpressVPN being one of them), use different kinds of packet obfuscation to avoid detection. I have several employees in different parts of China right now using ExpressVPN with OpenVPN successfully. They are not currently using a GLI Router, but I hope to be recommending them to purchase one in the future after I have completed my testing. If I can assist others with any information regarding VPN use in China (in general), and which providers are currently working there, I am glad to help. -Leon
