It seems to be quite hard to bypass Great Firewall of China using VPN. Tried it once and it didn't work.
32% of al chineese bypass the gfw on a daily bases.
So this is no big deal.
If they are clever enough to use Anti DPI. well, thats possible. Tried accessing facebook and twitter using various VPN and none of them worked.

You are simply not clever It looks! , Wise UP or die is the motto

....
34% of the chineese is more clever then YOU are

For DPI to work you Need a PATTERN

, if no pattern can be found DPI is USELESS!
You come from a western country so you never needed to protect , thinking gov is friend.
If a connection is random noise no DPI will help.
http://safesrv.net/setup-openvpn-with-obfsproxy-on-ubuntu/ https://forums.openvpn.net/topic12605.htmlIn Vietnam, VPN is used by 38% of the online population and in Brazil and Thailand 36%. Mexico, India and China all reported use by an estimated 34% of the population that has access to the internet, with the UAE and Argentina on 32%.
so only dummy's are stoped by firewals.
Ths also explains why chinese people are more skilled , then western people , in chine they deal with real problems.
Not as tech savvy as those people... Thanks for the tips though. Was trying to access from my Iphone 4S
