en	To open **Onion Circuits**, click on the Tor status icon ([[!img lib/symbolic/tor-disconnected.png alt="Tor status menu" link="no" class="symbolic"]] or [[!img lib/symbolic/tor-connected.png alt="Tor status menu" link="no" class="symbolic"]]) in the top-right corner and choose **View Tor Circuits**.

en	Understanding Tor circuits

en	If Tails is already [[connected to the Tor network|doc/anonymous_internet/tor]], a list of Tor circuits appears in the left pane of *Onion Circuits*.

en	Click on a circuit to display the technical details about each relay in the right pane.
es	Si seleccionas un circuito aparecerán detalles técnicos sobre los repetidores del circuito en el panel de la derecha.

en	Each Tor circuit is made of 3 Tor relays. In the example above, the connection to **tails.net** goes through the 3 relays **drk**, **kicka**, and **Quetzalcoatl**.

en	If you use a Tor bridge:

en	Tor uses the bridge as your entry guard.
es	Si tu configuraste un puente de Tor, tu puente es tu guardia de entrada.

en	If you don't use a Tor bridge:

en	Tor uses only 2 different relays as your entry guards, as a way of [protecting against *end-to-end correlation* attacks](https://support.torproject.org/about-tor/how-tor-works/entry-guards/).

en	Your entry guards change every time you restart Tails.

en	To keep the same entry guard across different Tails sessions, use a Tor bridge instead.

en	Tails restarts Tor and all circuits are replaced if you disconnect and reconnect from your local network, for example, by turning the Wi-Fi off and on again.
