 After the VPN connection has been established, the node should be able to reach
 the mesh's DNS servers and use these for all other name resolution.
 
+If the device does not feature a WAN port, the LAN port is configured as WAN port.
+In case such a device has multiple LAN ports, all these can be used as WAN.
+Devices, which feature a "hybrid" port (labled as WAN/LAN), this port is used as WAN.
+
+This behavior can be reversed using the ``single_as_lan`` site.conf option.
