To address this, the ProxySG will need to be configured as follows: It is possible to configure Tor with proxy settings in such cases, which attempts to bypass strict firewalls. Tor will no longer have direct access to the network. If your firewall does not perform packet inspection, Tor can simply tunnel requests through these ports, so only allowing the ProxySG access to the Internet will prevent this. This is the most restrictive method. It involves blocking all ports outbound on the firewall, allowing only common services such as HTTP\HTTPS. However, it will still communicate using encryption with untrusted certificates, so protocol-aware devices (such as the ProxySG) can interrupt this. Should the firewall block all attempts to connect to the Tor network, Tor will default to ports 80 and 443.
Users can configure Tor to use these bridge nodes which can be obtained from Tor (), or even via email. Blocking these root directory servers gives the appearance of blocking Tor -but advanced users will still be able to access the network through advanced Tor configuration.

Blocking the eight addresses is not effective since Tor also maintains bridge nodes - nodes which do not exist in the public directory and can be used to download other node locations. On initial install, Tor connects to eight hard-coded directory servers to obtain a list of known Tor nodes.

Microsoft Windows defaults to listening on port 9050, however other platforms are able to select dynamic ports at random to listen on. The SOCKS traffic is then sent encrypted through the Tor network. The application works by running a local SOCKS service that applications can connect to. Tor runs as an executable on a variety of platforms, including Microsoft Windows, MacOS, and Android. Note: an SSL license is required to effectively block Tor. Here is an overview of the Tor network and recommended methods to manage it on your network. Each has its own advantages and disadvantages, depending on the network topology you have deployed. There are two effective ways to block Tor on the ProxySG.
