I just returned to China after most of a year. The VPN stuff has gotten much worse. Tor is banned, new wacky Tor is banned. My work VPN (OpenVPN based, not publicly listed or used by anyone else) appears blocked (though it worked a couple of days back on a different link; I have a theory this is China Unicom vs. China Telecom landlines).
I am presently exploring IPSec/PPTP/SSH+PPP style solutions. Can anyone save me time here and tell me what is likely to be the most reliable? OpenVPN has been my mainstay in the past and it is now too much trouble here.
SSH+PPP is looking good from a low-latency, port-hopping, unlikely-to-be-blocked perspective, but figuring out how to get a client for that up in OSX is driving me nuts.
