MikroTik RouterOS is a highly flexible network operating system widely used by ISPs and businesses to manage their networks. For beginners, the initial configuration can feel confusing — but with the right guide, you can get started in minutes.
1. Reset to Factory Defaults
Start from a clean state using /system reset-configuration via Winbox or WebFig terminal.
2. Configure Interfaces & IP Addressing
Decide which interface is WAN and which is LAN. Assign a static IP or enable DHCP Client on the WAN interface as required by your ISP.
3. Set Up a DHCP Server for LAN
Enable a DHCP Server on the LAN interface so connected devices automatically receive an IP address, gateway, and DNS.
4. Configure NAT (Firewall Masquerade)
Add a NAT masquerade rule under IP > Firewall > NAT so local devices can reach the internet.
5. Secure Router Access
Change the default password, disable unused services, and restrict admin access to specific IPs.
With these five basic steps, your MikroTik router is ready as a stable internet gateway. For deeper learning, GLC Networks offers an official MTCNA training that covers this configuration comprehensively.
