XB8 Gateway URL blocking not working

The XB8 gateway just ignores the block.

@user_0948df Just to confirm, were these the steps you took to you apply the settings? 

Set up website blocking
To set up website blocking from the Xfinity WiFi Gateway's Admin Tool website, you may have to enable Admin Tool access. Visit Allow Xfinity WiFi Gateway Admin Tool online access using the Xfinity app.

Go to http://10.0.0.1 from your home network.
The default settings to open the Admin Tool are:
          Username: admin
          Password: Check the sticker on the bottom of your Xfinity Gateway for the password.
If you changed your Admin Tool password before, use your new login info. If you don't remember your Admin Tool password, you can contact Xfinity or factory reset your wireless gateway.
Go to Parental Control > Managed Services. The Managed Services menu allows you to prevent access to applications and services.
Select Enable, then:
Blocked Sites: Click Add and enter the URLs of the websites to be blocked, and set up a time schedule.
Blocked Keywords: Click Add and enter keyword(s) that appear on websites you want blocked, and set up a time schedule.

Yes, that is correct.
