How to Set Up a MikroTik Router from Scratch with script
Setting up a MikroTik router for the first time may seem complex, but following these steps will get your network online quickly.
1. Connect to the Router
- Connect your PC to the MikroTik router using an Ethernet cable.
- Download and open WinBox.
- Use Neighbor Discovery to find and connect to the router. [1]
2. Reset to Default (Optional)
- Go to System → Reset Configuration if you want a clean setup.
3. Configure WAN (Internet)
- Connect your ISP cable to ether1.
- If your ISP uses DHCP:
- Go to IP → DHCP Client
- Add DHCP Client on ether1.
4. Configure LAN
- Create or verify a bridge containing LAN ports.
- Assign a LAN IP (e.g., 192.168.88.1/24).
5. Set Up DHCP Server
- Go to IP → DHCP Server
- Click DHCP Setup
- Select the LAN bridge and follow the wizard. [2]
6. Configure DNS
- Go to IP → DNS
- Enable Allow Remote Requests
- Add DNS servers (8.8.8.8 and 1.1.1.1).
7. Configure NAT
- Go to IP → Firewall → NAT
- Add:
- Chain: srcnat
- Out Interface: ether1
- Action: masquerade
8. Secure the Router
- Change the admin password.
- Upgrade RouterOS to the latest stable version.
- Disable unused services.
9. Test Internet
- Connect a device to the LAN or WiFi.
- Verify that websites load successfully.
For businesses, I recommend adding:
- VLANs for network separation
- Firewall rules
- VPN access
- Hotspot or PPPoE services
- Automatic backups
These features make MikroTik ideal for offices, ISPs, hotels, schools, and enterprise networks. [5]
