#
# LightTPD server in a Wireguard VPN
#
# Once the scenario is running and DHCP is done, you can reach the server from
# your host system via 10.0.9.2:80 . The traffic is going through a host
# Wireguard device 'wg0' that puts it into an encrypted UDP tunnel towards the
# TAP device 'tap0' where it enters Qemu and reaches the inner Genode router
# at domain 'uplink'. The inner router port-forwards the traffic to its
# 'downlink' domain to which the tunnel side (10.0.3.2) of the Genode Wireguard
# component is connected . This component unpacks the original packets
# from the tunnel. The back side of the component is connected to the inner
# Genode router at domain 'uplink' and sends the plain packets unmodified a
# this connection. The routers IP identity in that domain is the Wireguard
# device IP, speak the VPN-internal IP 10.0.9.2 of the server. The inner
# router now forwards the different ports to the corresponding peers, in
# this case TCP port 80 to the LightTPD server (10.0.5.2) at the inner
# router domain "downlink".
