Preparations on the Vacuum Robots

The Dustcloud IP must be a public IP address and not from your locale LAN!

You don't need to host the dustcloud on a public IP though, you can just use any public address and then redirect the traffic on your vacuum robot.

1. Point your vacuum via /etc/hosts to your <my_cloudserver_ip>. <my_cloudserver_ip> can be 130.83.47.181 (this is a Server of the TU Darmstadt, content does not matter):

   0.0.0.0 awsbj0-files.fds.api.xiaomi.com
   0.0.0.0 awsbj0.fds.api.xiaomi.com
   130.83.47.181 ott.io.mi.com
   130.83.47.181 ot.io.mi.com
   

2. Execute on vacuum:

   iptables -t nat -A OUTPUT -p tcp --dport 80 -d 130.83.47.181 -j DNAT --to-destination 192.168.42.42:80
   iptables -t nat -A OUTPUT -p udp --dport 8053 -d 130.83.47.181 -j DNAT --to-destination 192.168.42.42:8053

   where 192.168.42.42 is the IP of your local instance and the port number on which server.py runs (can technically run on a Raspberry pi).
