MikroTik: Configure static IP Address on the Interface

Introduction

Setting up a static IP address on a MikroTik interface is a fundamental networking task that ensures consistent connectivity and seamless communication within your network. This guide provides clear, step-by-step instructions to configure a static IP address and optimize your MikroTik router settings.

Why Configure a Static IP?

Assigning a static IP address is crucial for devices requiring reliable access, such as servers, printers, or management interfaces. Unlike DHCP-assigned addresses, a static IP ensures that your network services remain uninterrupted and easily accessible.

Step-by-Step Static IP Configuration with WinBox

Step 1: Log in to MikroTik Router

Access your router via the MikroTik WinBox application or the web interface. Use your credentials to log in.

Step 2: Navigate to the Interface

Open the IP menu and select Addresses.

• In WinBox, this is found under IP > Addresses.

Step 3: Add a New Address

• Click on the + button.
• Enter the static IP address in the format: 192.168.x.x/24.
  • If you are not sure what is Netmack and Adress you can check the link.
• Select the desired interface (e.g., ether1).

Step 4: Apply and Verify

• Click Apply and OK.
• Check the configuration under IP > Routes to ensure the new static IP is functional.

Configuration via CLI

Using the MikroTik Command Line Interface (CLI) is an efficient way to configure a static IP address. Here’s a step-by-step guide:

Step 1: Access the MikroTik Router

• Open a terminal or use an SSH client (e.g., PuTTY) to connect to the MikroTik router.
• Login with your username and password.

Step 2: Navigate to the IP Address Configuration

Enter the following command to access the IP address settings:

/ip address

Step 3: Add the Static IP Address

To assign a static IP address to a specific interface, use the following command:

add address=192.168.x.x/24 interface=ether1

• Replace 192.168.x.x/24 with the desired IP address and subnet mask.
• Replace ether1 with the name of the interface where you want to assign the IP.

Step 4: Verify the Configuration

Check the assigned IP addresses using:

print

This will display a list of all configured IP addresses, along with their interfaces.

Step 5: Test Connectivity

• Use the ping command to test if the configured IP address is reachable:

ping 192.168.x.x

Example Configuration

To assign the IP 192.168.1.1/24 to the interface ether1, you would run:

/ip address add address=192.168.1.1/24 interface=ether1

Troubleshooting Tips

1. Verify cable connections
2. IP Not Reachable – Ensure no conflicting IPs exist.
   • Ensure no other devices are using the same IP address.
3. Firewall Rules
   • Ensure no firewall rules are blocking traffic to the new IP.
   • Check firewall or NAT settings.

Best Practices

• Use a subnet that matches your network structure.
• Avoid conflicts with DHCP ranges.
• Test connectivity by pinging the configured interface.
