-# Point-to-Point Tutorial
-
-## Goals
-* Connect several single nodes via a VPN
-* Nodes should be able to reach each others even through NATs
-* Traffic should be secured with a password
-* Nodes should be accessible by IP addresses and names like `NODE.myvpn`
-
-
-## Preparations
-To be able to set up the VPN, at least one node needs to be reachable by an
-unchanging address of hostname. This is normally not the case with common
-DSL uplinks (they change addresses every day).
-To mitigate this problem and get a fixed hostname, there are services called
-dynamic DNS or short DDNS. There are lots of [different DDNS services][1], some
-are free, some cost money.
-Most of those services provide a common API that can be used by freely available
-tools to update the address whenever it changes. Mainstream DSL routers have
-built-in clients for this API so nothing has to be installed to set up DDNS.
-
-Besides this unchanging address, a port has to be opened for VpnCloud. This has
-to be done in the settings of the DSL router. The default port for VpnCloud
-is 3210. This process is different for every router but it usually can be found
-under the name of "Port forwarding" or "Exposed ports" (not "exposed host").

-## 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 to start with in `/etc/vpncloud/example.net`.
-
-    $> sudo cp /etc/vpncloud/example.net /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. Several addresses can be appended
-  and separated by spaces like `"node1.dyndns.org:3210 node2.dyndns.org:3210"`.
-  All nodes that have an unchanging address should be listed 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.
-
-- **ENABLED**: This needs to be set to `1` when everything is finished so the
-  network is started automatically.
-
-After the config file has been set up correctly, VpnCloud needs to be restarted:
-
-    $> sudo /etc/init.d/vpncloud restart
-
-Finally, on each host the names of the nodes should by associated with their
-address. This can be done by editing `/etc/hosts`:
-
-    $> sudo nano /etc/hosts
-
-For each node a line with `NAME.myvpn 10.0.0.X` needs to be added.
-
-
-## Testing the network
-When everything has been setup properly, the connection can be checked using the
-`ping` command:
-
-    $> ping NAME.myvpn
