My personal suggestions for the Netduma:
- some more slots for devices in the geofilter section (1 geofilter for 4 devices is not enough for me ;-) )
- a seperate geofilter for each device slot
- user-defined geofilter settings (-> geofilter by port range for e.g. udp 10000-65535)
- WiiU geofilter WITH ping assist
- Connection viewer (IPs, ports, amount of data sent/received = the same feature is present in OpenWRT)
- Selection to ban servers temporarily or for permanent (no bad dedicated server again)
- Instead of the Ping diagnosis test pinging 8.8.8.8 to see the last mile ping, just run a link in the browser to the site www.dslreports.com with pre-defined settings for advanced testing results (such as bufferbloat, quality and speed)
- restart the Netduma automatically once a day at a user-defined time of the day to refresh the device status
- hide the SSID of the wifi network thus making it harder for amateur hackers to spot your network and put it at a risk
That's it.
