-----------------------thank you valens ... i have another question, can we register or put our client ip address in some kind of ip table in the router? FYI, i use mikrotik OS 2.8.28. Thank you
btw, i already did what u've suggested, but the ip i want to drop or reject is still in my firewall connections table, they still have access to the internet.
Isnt your rule will drops every ip except one pair MAC+IP ? I mean it will work only for one client.Friend, you should read the manual first before asking here.
But, you can try using mac address protection:
/ip firewall filter add src-mac-address=[client mac address] src-address=![client correct ip address] action=drop
Gotmoh, I didn't check my script yet, and never use it before.Isnt your rule will drops every ip except one pair MAC+IP ? I mean it will work only for one client.
Im using construction with lotof pass rules. One pass rule for one MAC+IP pair. At the end i have one rule to drop everyting whats not equal to previous passing rules.
