====== Tunneling ======
A tunnel is a connection between two AREDN nodes that uses the Internet instead of RF, where an RF isn't possible due to geography.  It's also possible to use a tunnel as a backup connection, which can be useful if conditions change.

In order to setup a tunnel connection between two AREDN nodes, one node needs to act as the server, and the other as the client.

Most nodes are configured as Tunnel Clients, and they connect to a central Tunnel Server.

**Most end-user nodes will be configured as Tunnel Clients.**

This provides you with a connection to the mesh.

See the current [[../tunnel_list/ |list of tunnels]] to know who to contact.  Reach out to an operator with an existing Tunnel Server for connection details.

======  OLD UI ======
===== Server Side =====
In this example, VA7FI-HAP-1 is the server and VE7RBE-HAP-1 is the client (and the details are made up):


On VA7FI-HAP-1's ''Tunnel Server'' page:
{{ server.png }}

  * **Client**: ''VE7RBE-HAP-1'' is Robert's node name.
  * **Pwd**: Create a unique password for that node.
  * **Net**: ''172.31.39.164'' is automatically assigned by the hAP.
  * Some optional contact info can be added.

In addition to this information, VA7FI's public IP address will also need to be given to VE7RBE.  To find your public IP address quickly, you can simply search for "what's my ip" in your favourite search engine:

<WRAP half column>
[{{google.png|Search for "what's my ip" in [[https://www.google.com/search?q=what's+my+ip |Google]]}}]
</WRAP>

<WRAP half column>
[{{ddgo.png|Search for "what's my ip" in [[https://duckduckgo.com/?t=lm&q=what's+my+ip |DuckDuckGo]]}}]
</WRAP>
\\

===== Client Side =====
On VE7RBE-HAP-1's ''Tunnel Client'' page:
{{ client.png }}

  * **Server**: ''154.12.201.102'' is VA7FI-HAP-1's public IP address
  * **Pwd**: is the password created by VA7FI
  * **Network**: ''172.31.39.164'' is the **Net** address automatically generated by VA7FI-HAP-1
