Direct access to the Tor network may sometimes be blocked by your Internet Service Provider or by a government. Tor Browser includes some circumvention tools for getting around these blocks. These tools are called “pluggable transports”.

TYPES OF PLUGGABLE TRANSPORT

Currently there are three pluggable transports available, but more are being developed.

obfs4 Cuireann obfs4 cuma randamach ar thrácht Tor, agus cuireann sé cosc ar chinsirí droichid a aimsiú trí scanadh an Idirlín. Níos lú an seans go gcuirtear cosc ar dhroichead obfs4 ná ar dhroichead obfs3.
meek meek transports make it look like you are browsing a major web site instead of using Tor. meek-azure makes it look like you are using a Microsoft web site.
Snowflake Leagan feabhsaithe de Flashproxy is ea Snowflake. Seolann sé do chuid tráchta trí WebRTC, prótacal ó ríomhaire go ríomhaire a bhfuil cumas tollta NAT ionsuite ann.

USING PLUGGABLE TRANSPORTS

To use a pluggable transport, click "Configure Connection" when starting Tor Browser for the first time. Under the "Bridges" section, locate the option "Choose from Tor Browser's one of built-in bridges" and click on "Select a Built-In Bridge" option. From the menu, select whichever pluggable transport you'd like to use.

Once you've selected the pluggable transport, scroll up and click "Connect" to save your settings.

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 the option "Choose from Tor Browser's one of built-in bridges" and click on "Select a Built-In Bridge" option. Choose whichever pluggable transport you'd like to use from the menu. Your settings will automatically be saved once you close the tab.

WHICH TRANSPORT SHOULD I USE?

Each of the transports listed in Tor Bridge's menu works in a different way, and their effectiveness depends on your individual circumstances.

If you are trying to circumvent a blocked connection for the first time, you should try the different transports: obfs4, snowflake, or meek-azure.

If you try all of these options, and none of them gets you online, you will need to request a bridge or manually enter bridge addresses.

Users in China will likely have to connect with a private and unlisted obfs4 bridge. Contact our Telegram Bot @GetBridgesBot and type /bridges. Or send an email to frontdesk@torproject.org with the phrase "private bridge" in the subject of the email.
