You know when i first heard I was going to china that's the first site I went to. I ended up clicking on the second of his recommended links. That provider gives some 18 different chinese dedicated VPN servers which they bounce through various cdns, and provide a further 18 others. On their knowledge base and using their own dedicated vpn software they say in order of preference to try OpenVPN on TCP 443, UDP, and lastly L2TP.
My own experience when I first got here L2TP didn't work at all. Not to this VPN, not to my home network. PPTP worked sporadically to this VPN, and seemed to work consistently to my home. OpenVPN worked reliably with the exception that they detect the network and reset it occasionally (like every 2 hours, but auto-reconnection in the client takes care of that). It's really only been the past 3 days I have had any issue with OpenVPN and found that L2TP has worked at all.
You found links claiming otherwise? Great. Thanks for sharing, the information may come in handy. But right now I can only offer you what I have been experiencing the past month.
