-====== Tunnelling ======
-In order to setup a tunnel connection between two AREDN nodes, one needs to act as the server, and the other as the client.  In this example, VA7FI-HAP-1 is the server and VE7RBE-HAP-1 is the client (and the details are made up):
-===== Server Side =====
-On VA7FI-HAP-1's ''Tunnel Server'' page:
-{{ :howto:aredn:tunnelling:server.png }}
-From left to right:
-  * Client: ''VE7RBE-HAP-1'' is Robert's node name.
-  * A unique password is created
-  * Net: ''172.31.39.164'' is automatically assigned.
-  * Some optional Contact Info can be added.
-VA7FI's public IP address will also need to be given to VE7RBE.  To find your public IP address quickly, simple search for "what's my ip" in your favourite search engine:
-|<100% - ->|
-^  [[https://www.google.com/search?q=what's+my+ip |Google]]  ^  [[https://duckduckgo.com/?t=lm&q=what's+my+ip |DuckDuckGo]]  |

-===== Client Side =====
-On VE7RBE-HAP-1's ''Tunnel Client'' page:
-{{ :howto:aredn:tunnelling:client.png }}
-From left to right:
-  * Server: ''154.12.201.102'' is VA7FI-HAP-1's public IP address
-  * Pwd: is the password created by VA7FI-HAP-1
-  * Network: ''172.31.39.164'' is the net address generated by VA7FI-HAP-1
-===== More About Public IP Addresses =====
-Most residential internet services are given a single //dynamic// IP address, which means that the address can //change// every few days or so, or when the router power cycles.  This means that when a server node suddenly gets a new public IP address, the client node can't find it anymore.
-One solution is to use a [[wp>Dynamic_DNS]] service like [[https://noip.com|No-IP]].  These services query your //dynamic// IP address, and translate it into a //static// hostname.  It's that hostname that you can then give the AREDN client (instead of your public IP address).
-However, there's an extra step required for the No-IP service to query your dynamic IP address.  This can be done by installing a small program on your computer, but some routers have that option their settings.  For example: on my Telus T3200M router, I can enter my No-IP information under:
-''Advanced Setup'' -> ''Dynamic DNS''
-{{ :howto:aredn:tunnelling:dynamicdnsmodem.png }}
-So with this setup, VE7RBE would use ''myfancyhostname.ddns.net'' instead of ''154.12.201.102'' as the Server address, and every time my router gets assigned a new public IP address, it'll be able to notify No-IP, which will update it so that ''myfancyhostname.ddns.net'' continues to point to my router.
