What is Mikrotik Router? Mikrotik Router Configurations – DHCP Server Installation

It is a Router Operating System which is developed on Mikrotik Linux kernel and requires a license. With this operating system, you can turn your pc-based computer into a modern router, a VPN server or a high-spec firewall. This product is generally preferred by web hosting companies, medium-sized businesses and networks with low traffic.

Mikrotik Router Configuration

Mikrotik devices allow connections through ssh, telnet, web and winbox applications at first installation. You can download the Winbox application from its site. You can connect over Winbox via MAC and IP address. In the first installation, the username “admin” password part is blank.

DHCP Server Installation

To activate the DHCP service over ssh, after we have given the “ip dhcp-server setup” command, a guide will come to determine the IP pool, Gateway and DNS addresses and lease time. You can take a look at the picture below to install it via Winbox.

Firewall rules

We need to write a rule in the firewall to limit the connection requests from outside ports that we do not want. We will allow ICMP, SSH, and Winbox ports. At the same time, we will drop requests from the connection status that do not perform the triple handshake steps of the TCP.
