I used the parental control to restrict the time my son is using the internet for gaming.

In the beginning that worked well, but then he started to use free VPN's to bypass the parental control.

So I started to block these VPN's, and soon I reached some limits related to max blocked sites.

Then he started with something new, he installed a tool to change his MAC address.

By default the DECO accepts every device when you connect via a LAN cable or as long as you have an user name / password.

So by using a new MAC address he started to bypass every restriction.

Then I started to black list all these "new" devices.

Then he just retrieved the MAC address of my wife etc. and changed his MAC address to that one.

I have given up. Internet is fully open without any restriction.

Instead we talk... or switch off the internet by disconnecting the main internet cable.

Change request:

Option that devices can only connect to the main network via the LAN cable if the MAC address is whitelisted

Option that devices can only connect to the main network via the WIFI if the MAC address is whitelisted (and they know the WIFI password)

Devices can still connect to the guest network if they know the WIFI password (so no change)

By whitelisting the MAC addresses we can prevent that everyone can just connect to the main network with "new" devices. We can enable the guest network only when there are guests. This change partly prevents bypassing parental control by changing the MAC address, as they can still change it to your MAC addresss...
