Great Firewall 升咗呢，全面封殺 OpenVPN

keaniny

頂，呢個星期，大陸個 Great Firewall 好明顯 upgrade 咗，全面封殺 OpenVPN ~
搞到 TLS Handshake 唔成功，轉過另一個 port 後，過兩日又封殺過 ~

而加試用 stunnel 扮 HTTPS traffic, 希望避過 DPI 啦 ~

我係琛圳只係用 PPTP都無事.

我個 case 係 site-to-site VPN, 轉咗 port 都要兩日倒先至駁唔返 ~
pptp 個人認為可免則免，L2TP/IPSec 要快啲上手至得 ~

Exactly 我個 case ...

最近在試 openvpn, 一部 N16, 一部 N12, 一 connect, client totally freeze, 要 hard reset, 都不知道原因.

Anyone tried openvpn with obfsproxy yet?  

Also, a very good reading about the GFW:

Tried with great success.
It has survived for 5 days already.

However, in order to work with obfsproxy, I need to change the UDP to TCP. Plus the overhead obfsproxy added, the VPN is just usable in the file-replication, but not for my SIP phones.
