Fixed & Restrict MAC & IP Address to access internet

RouterOS Beginner Basics
1

Hello Everyone, I am new and this is my first post. I found a router board 450G. I am facing two problem and couldn’t find the solution from any place.

  1. I found RB450G router board but confused about it. I am unable to check is it RB450G or RB450? there are any command to check the version of this router?

when I have logged in my router and system>resource I found CPU Freq=300 MHz, Board=450, Total Memory 60.9MiB, Total HDD=61.4MB


2) I configured basic internet sharing, bandwidth limit by this router. But I want to know how to fixed IP & MAC address can access internet? I mean only my listed IP & MAC user can access internet on the network.

I want if the users MAC & IP will be same as my listed ip table then he can access internet.

Please share if any one have this solution.

thanks in advance.

by the specs, it is RB450, however you can know for sure when you do ‘/system routerboard print’ command. Output (window) will show a model name.

about your second issue - you can create an address list for local hosts and allow only these hosts in firewall, or you can add static ARP entries and set ARP on the interface to static.

you can read about these more on wiki.mikrotik.com

Thank you for your reply. I chacked that command for issue 1 and got that information which on provided before.

For second issue, i tried by static ARP entries and set ARP on the interface to static. I found a problem.

  1. suppose my (client_ip=192.168.1.5) I used it as static ARP entries.
  2. after that I changed my client IP address to another IP address (client_new_ip=192.168.1.6).
  3. now when I check ARP entries I found the new IP address with previous MAC address and can check internet by this new ip..

where is the problem?

I think i have to check ur first option for 2nd issue. I have to create address list on firewall but not sure about it.
thanks.

After make static ARP you need to do make static in DHCP .
Go to DHCP lease and make static the ip address that you want to access for Internet.
Go to ur PC and change ur ip address.No more Internet.
Enjoy!
