-
-Three single nodes should be connected via a secure VPN. `node1` and `node3` have fixed addresses but `node2` has a dynamic address that changes regularly.
-
-
-#### Note
-To be able to set up the VPN, at least one node needs to have a be reachable by an
-unchanging address of hostname. This is normally not the case with common
-DSL uplinks (they change addresses every day). Please see [[Dynamic DNS]] for
-a solution.
-
-
-## Setup
-The actual VpnCloud setup is pretty simple.
-
-A new network config in `/etc/vpncloud` has to be created on each node.
-There is an example file in `/etc/vpncloud/example.net.disabled` that explains all the parameters.
-
-    $> sudo cp /etc/vpncloud/example.net.disabled /etc/vpncloud/mynet.net
-
-Now that file has to edited to change a few values:
-
-    $> sudo nano /etc/vpncloud/mynet.net
-
-The following values have to be modified:
-
-- **peers**: This is a list of all peers that this node should connect to.
-  Only unchanging addresses can be used here.
-
-- **shared_key**: This is a shared password for all nodes that secures the
-  communication. It must be the same on all nodes and of course it should be a
-  strong password.
-
-- **ifup**: `ifconfig $IFNAME 10.0.0.X/24 mtu 1400` where `X` is different for
-  every node. It is good idea to use incrementing numbers here and to track the
-  assigned numbers and nodes in a list.
-
-This leads to the following configuration files:
-
-#### Node1
-    peers:
-      - node3.example.com
-    shared_key: "mysupersecretkey"
-    ifup: "ifconfig $IFNAME 10.0.0.1/24 mtu 1400"
-
-#### Node2
-    peers:
-      - node1.example.com
-      - node3.example.com
-    shared_key: "mysupersecretkey"
-    ifup: "ifconfig $IFNAME 10.0.0.2/24 mtu 1400"
-
-#### Node3
-    peers:
-      - node1.example.com
-    shared_key: "mysupersecretkey"
-    ifup: "ifconfig $IFNAME 10.0.0.3/24 mtu 1400"
-
-
-After the config file has been set up correctly, VpnCloud needs to be started:
-
-    $> sudo service vpncloud@mynet start
-
-If you want to, you can [[associate names with the nodes|Naming Hosts]]. Please note that this procedure has to be done on all nodes.
-
-
-## Testing the network
-When everything has been setup properly, the connection can be checked using the
-`ping` command:
-
-    $node1> ping 10.0.0.2
-    $node2> ping 10.0.0.3
-    $node3> ping 10.0.0.1
-
-
-## Advanced settings
-- **crypto**: This setting defines the used encryption method. Options are `chacha20` (the default) and `aes256`. Both are pretty secure but `aes256` is only supported on newer CPUs (check support with `vpncloud -V`). If all nodes support `aes256` the method can be changed and might bring some speed improvements.
-- **magic**: This setting can be changed to hide the protocol header and make VpnCloud undetectable. This setting must be the same on all nodes.
