+      nat-traverse establishes direct connections between nodes which are
+      behind NAT gateways, i.e. hosts which do not have public IP addresses.
+      This is done using an UDP NAT traversal technique. Additionally, it's
+      possible to setup a small VPN by using pppd on top of nat-traverse.
+
+      nat-traverse does not need an external server on the Internet, and it
+      isn't necessary to reconfigure the involved NAT gateways, either.
+      nat-traverse works out-of-the-box.
