大多数可插拔传输,比如 obfs4,依赖于“网桥”中继。
如同普通的 Tor 中继,网桥由志愿者经营;然而,与普通中继不同,它们并未公开列出,因此对手无法轻易识别它们。
结合使用网桥和可插拔传输器有助于掩盖您正在使用 Tor 的事实,但与使用普通 Tor 中继相比,可能会减慢连接速度。
其他可插拔传输层(例如 meek)使用不同的抗审查技术,不依赖于网桥。您不需要为了使用这些传输而获取网桥地址。
获取网桥地址
因为网桥地址非公开,您需要自行请求。您有两个选项:
使用MOAT
If you're starting Tor Browser for the first time, click on "Configure Connection" to open the Tor settings window.
Under the "Bridges" section, locate "Request a bridge from torproject.org" and click on "Request a Bridge..." for BridgeDB to provide a bridge.
完成验证码并点击“提交”。点击“连接”以保存你的设定。
Or, if you have Tor Browser running, click on "Settings" in the hamburger menu (≡) and then on "Connection" in the sidebar.
In the "Bridges" section, locate "Request a bridge from torproject.org" and click on "Request a Bridge..." for BridgeDB to provide a bridge. Complete the Captcha and click "Submit". Your setting will automatically be saved once you close the tab.

输入网桥地址
If you're starting Tor Browser for the first time, click "Configure Connection" to open the Tor settings window.
Under the "Bridges" section, from the option "Enter a bridge address you already know" click on "Add a Bridge Manually" and enter each bridge address on a separate line.
点击“连接”来保存你的设置
Or, if you have Tor Browser running, click on "Settings" in the hamburger menu (≡) and then on "Connection" in the sidebar.
In the "Bridges" section, from the option "Enter a bridge address you already know" click on "Add a Bridge Manually" and enter each bridge address on a separate line.
当你关闭标签页时你的设定会自动保存。

如果连接失败的话,可能是因为您所指定的网桥目前并非正常运作中,请使用上面所提的方法获取更多的网桥地址后,再行尝试。
