That functionality (Remote administration), is almost certainly turned OFF in your router settings.
For good reason.
You being able to access it from outside means that someone else might be able to as well.
However...some ISPs allow access to some router functions through your account...the same place where you pay the monthly bill.
Also, does the router have a Parental Control function? Often, you can setup a time schedule.
Only ON between the hours of X and Y, for individual devices.
