Block Internet access - MAC-address

RouterOS Beginner Basics
1

Sorry for newbie question. Mikrotik with RouterOS (6.42.3).

I’ve tried to set up a rule for blocking internet access for a MAC-address. This is the code I used to test it. I wanted it to be active for one minute every day, between 13:12 and 13:13:

/ip firewall filter add chain=forward action=drop time="13:12:00-0h1m,mon,tue,wed,thu,fri,sat,sun" src-mac-address=00:00:00:00:00:00

It blocks Internet access, but for some reason the block is active until I manually deactivate it. So I think I might be making a logical mistake.

I looked at Kid-Control, but this block looked easier to set up.

The right question to ask, is if time control works on an already active sessions.
In other words if a connection is made prior to the time set, will the activity be cut-off or allowed to continue (only affects NEW sessions after time start of cutoff).

Can you identify the IP of the lan device or just the mac?
You can set mac to statically get the same IP…

I’m not sure I understand your point. The filter rule works so far that the Internet access is blocked, but the rule never stops to run unless I manually disable it.

I can identify the IP-address, but I guess I need two rules, one for ipv4 and one for ipv6.

I found the rule for MAC address in this thread:
