What is the configuration for port forwarding with multiple ports. These are UDP For eg: 16384:32768. Or 16384-32768 or something else. It seems to accept anything.

  Update: Not sure you can add multiple ports via the interface.  Maybe something that should be looked at if you can't.  So i added the appropriate ports using:

  sudo iptables -t nat -A PREROUTING_PORT_FORWARD -p udp -d <Firewalla IP> --dport 16384:32768 -j DNAT --to-destination <destination IP>:16384-32768

   

  To remove them just replace the -A with -D

  Lets hope its not messed up...:-)
