Hello, stupid question - I have a few clients on WLAN interface (everything works as I want) of Mikrotik and I need for them make excetions like this (pass them on, others not)
client 1 with MAC: 00:16:6F:2C:A8:A4 pass
client 2 with MAC: xxxxxxxxxxxxxxxxxx pass
client 3 with MAC: xxxxxxxxxxxxxxxxxx pass
etc…
and OTHERS NO.
and the stupid qeustion - How to create this ? 
thank you
Radek
Hello brychtak,
Here you have the answer
http://wiki.mikrotik.com/wiki/How_to_secure_a_network_using_ARP
If need anything else let me know
thank you, well this will work but one thing is not ideal… behind the mikrotik is dhcp server… So topology is client (wirelless) → mikrotik AP → Network with dhcp server (etherneet).. But i understand that this topology isn’t good. Should be better to move dhcp server to mikrotik or disable it and use static address… probably the best solution.

Try to use ip/DHCP relay
