Hi everybody
I kindly ask you for some help.I have a client who connect to my mikrotik server using pppoe and i want to reject him by his mac address.Do anybody have an idea how to make it?

/ip firewall filter add chain=forward src-mac-address=(user mac) action=drop disable=no

/ip firewall filter add chain=forward src-mac-address=(user mac) action=drop disable=no

It is not working with me

Then disconnect his cable from your network

chain=input, not forward

Chupaka, thanks for fixing my answer. Yes it should be input, sorry for the wrong answer.

Thanks

As I said before this don't work with me.But I think is it because my authentication server is not a Mikrotik based machine.
Strange but if I try with local user and pass set on the machine it still don't work .Did it work with you?
