Use of the TOR browser in TightGate-Pro

TOR is an overlay network for anonymising connection data. It is used for TCP connections and can be used in TightGate-Pro for anonymous surfing on the Internet. Tor protects its users from having their data traffic analysed. It is based on the idea of onion routing. TOR was originally an acronym for The Onion Routing.

At TightGate-Pro, m-privacy GmbH offers the TOR browser as an optional package. In this optional package, the TOR browser contains a TOR proxy and the version of the TOR browser preconfigured by the TOR project (Mozilla Firefox ESR). Details about the design of the TOR browser can be found on the Tor Project website at the following link: https://2019.www.torproject.org/projects/torbrowser/design/

Due to its architecture and functionality, the TOR browser has some special features that should be taken into account when preparing to use the TOR browser at TightGate-Pro. A description of how the TOR network works can be found at the TOR project under the following link: https://tb-manual.torproject.org/de/about/

The architecture of the TOR browser means that TightGate-Pro either has free access to the Internet (port 443 TCP) when using the TOR browser or an SSL/https-capable proxy must be set as an uplink proxy at TightGate-Pro.

Please make sure that:

• TightGate-Pro can either connect directly to the Internet (port 443 TCP protocol) or that an SSL-capable proxy is used for TightGate-Pro –> Link to set the proxy settings in TightGate-Pro .
  If TightGate-Pro can connect freely to the Internet, a non-SSL-capable proxy can also be entered as a proxy in TightGate-Pro. The proxy is then used for all connections with Firefox and Chrome and the TOR browser connects directly to the TOR network via the free Internet access.
• The proxy must be up-to-date atTightGate-Pro.

To install the TOR browser at TightGate-Pro, please proceed as follows:

• Login as administrator update

Assigning the TOR browser to identifiers

The TOR browser in TightGate-Pro can be accessed in two different ways. Firstly, the browser can be started directly via the start menu in the directory Internet directory or you can add a new icon to the menu bar for individual users or user groups to start the TOR browser.

• Login as administrator maint
• Select the menu item User administration → Menu options:
• Please select the ID or group to which you want to assign the TOR browser icon.
• In the interface menu options, select tor in the interface menu options. The selection is made with the space bar.
• Once selected, the new icon can be used and will appear on the menu bar the next time you log in via TightGate-Viewer.

Start and first connection

• The TOR browser is started by clicking on the new icon on the menu bar.
• The TOR browser then opens with the following start screen:
  
• Although the start screen prompts you to connect, this is not necessary as the connection has already been established automatically in the background. It is also not necessary to configure the TOR network settings, as all settings are already preconfigured. As usual, a desired URL can be entered in the address bar of the browser.
