If you live in an area with little or no Internet censorship, you may want to run a simple Tor relay or a Tor bridge relay to help other Tor users access an uncensored Internet.
The Tor network relies on volunteers to donate bandwidth. The more people who run relays, the faster and more secure the Tor network will be. To help people using Tor bypass Internet censorship, set up a bridge relay rather than an ordinary relay.
Bridge relays (or "bridges" for short) are Tor relays that are not listed in the main (and public) Tor directory. Even if an ISP is filtering connections to all the known Tor relays, it probably will not be able to block all the bridges.
There are only a few prerequisites for running a Tor relay:
What is not required:
To download Tor, go to the http://www.torproject.org/ Web site and click "Download" in the navigation menu.
On the "Available Tor Bundles" page, select the stable version that fits your operating system.
Launch the installer and click "Next" when asked.
If you are using Firefox, install all the components proposed in the dialog shown below:
If you do not have Firefox installed, deselect "Torbutton" (you will have the option to install Firefox and Torbutton afterwards).
When the installation is completed, launch Tor by clicking "Finish" with the "Run installed components now" box selected, as in the dialog shown below:
To activate your bridge:
Congratulations. If all has gone well, your bridge is up and running. Your bridge information will be added to the hidden bridge directory and made available to users who request it.
If you specifically established your bridge to help a friend access the Tor network, you can copy the information at the bottom of the Settings window and send it to him/her.
