Hi
can I make MT only to accept network users that I make in dhcp lease?
I mean to bind them to their mac address and only with that ip and mac addr he or she 
can use network, ive got mostly wifi users but it can be used for eth users too, if that could be done ofcorse…
P.S. Im a little suspicious about “ofcorse” maybe I misspeled it…
you mean to accept users with specific mac address (and assigned IP address), configure firewall rules to accept desired users.
You can use radius or create static leases.
For your wireless you can MAC filter.

No radius please Im a rookie .
yeah I meant to manage somehow… just one IP with exact one mac address can associate and if IP of that mac addr is changed user cannot be associated…
configure firewall filter forward, allowing to bypass users with specific MAC address and IP address configuration.
Use static ARP entries.. set ARP to reply only on your LAN interface then build your ARP table to match your users’ MAC and IP addresses.
alternative configurations 
Thank you
