By \u2018ignore\u2019 instead of \u2018bypass\u2019, we mean working without intermedia server.scholarzhang is a great attempt, but currently it hardly work. scholarzhang contain three parts: zhang(client-side connection obfuscation), cui(server-side connection obfuscation), gfw(drop gfw dns hijacking packets) (ref<\/a> \u9879\u76ee\u8ba1\u5212). On the client, we need to run zhang & gfw. The difficult part is that, GFW send RST packages to both ends, client & server, and Mr. zhang is trying to save reuse the connection after server received RST package(ref<\/a>), \u6211\u4f30\u8ba1 CUI \u4e5f\u662f\u5728\u5c1d\u8bd5\u505a\u7c7b\u4f3c\u7684\u4e8b\u60c5.

However, if Miss Cui make a move to help Zhang in, and this will make the task much easier. In fact, Ignoring the Great Firewall of China<\/a> and \u897f\u53a2\u8ba1\u5212\u539f\u7406\u5c0f\u89e3<\/a> both mention a way to ignore GFW: just ignore and drop the RST packges sent by GFW.<\/p>\n
