This is a small howto play Dune Emperor in LAN Multiplayer mode with the nodes sitting in different subnets. We use the udp forwarding feature of Cisco („ip helper“) to unicast forward the initial game setup broadcast packets from the client to the game host.


  • At least 2 Dune Emperor Games
  • At least 1 Cisco router or multilayer switch
  • handle your cisco gear with care!
