How to Configure MikroTik Router for Internet Access

To understand how to configure a MikroTik router for internet access, you must recognize that MikroTik routers are powerful tools. They help in setting up and managing network connections, including Internet access. If you’re new to MikroTik, configuring it to connect to the Internet can seem challenging. However, by following a few key steps, you can easily set up Internet access for your network.

Step: Configure Internet Access on MikroTik Router

In this guide, we’ll walk through the basic configuration steps. These steps include setting up WAN and LAN interfaces, configuring NAT, and adding a DNS server. By the end, your MikroTik router will be ready to connect your devices to the Internet.

1. Access the Router

• Open WinBox or the MikroTik WebFig interface.
• Connect to your router using the default IP (usually 192.168.88.1) and login with the default credentials (username: admin, no password).

2. Configure the WAN Interface

• Go to IP > DHCP Client.
• Click Add (+), then select the interface connected to your ISP (usually ether1).
• Enable the options Use Peer DNS and Use Peer NTP.
• Click Apply and OK. The router should now receive an IP from your ISP.

3. Configure the LAN Interface

• Go to IP > Addresses.
• Click Add (+) and set the LAN IP (e.g., 192.168.88.1/24) on the interface for your local network (usually ether2).
• Click Apply and OK.

4. Set Up a DHCP Server for LAN

• Go to IP > DHCP Server and open the DHCP Setup wizard.
• Select the LAN interface (e.g., ether2) and follow the wizard steps, ensuring it provides IP addresses within your LAN IP range. Following this will be key in how to configure MikroTik router for Internet access.

5. Set Up NAT (Network Address Translation)

• Go to IP > Firewall > NAT.
• Click Add (+) to create a new rule.
• Under the General tab, set Chain to srcnat, and in the Out. Interface, select the WAN interface (e.g., ether1).
• Go to the Action tab and select masquerade.
• Click Apply and OK. This step allows your internal network to access the Internet. It does this by translating local IPs to the public IP. This process is a key step in configuring your MikroTik router.

6. Configure DNS Settings

• Go to IP > DNS.
• Check Allow Remote Requests to enable DNS resolution.
• Set Servers to a reliable DNS, such as 8.8.8.8 and 8.8.4.4 (Google DNS), or use your ISP’s DNS servers.
• Click Apply and OK.

7. Test the Internet Connection

• Go to New Terminal and type ping google.com to test Internet connectivity.
• If the ping is successful, your router is now connected to the Internet and can provide access to connected devices.

By following these steps, you’ve successfully configured your MikroTik router to access the Internet. This setup provides a basic Internet connection for your network. It serves as a foundation for more advanced configurations, such as enhanced security and traffic management. Feel free to experiment with different features in RouterOS to get the most out of your MikroTik router!

MikroTik Router and Cisco

1. The Foundation: Same Networking Concepts

This is the most important point. Both Cisco IOS and MikroTik RouterOS are built on the same universal networking principles.

• OSI Model: They both operate on layers 2 (switching) and 3 (routing).
• Protocols: They implement standard protocols like OSPF, BGP, VLANs (802.1Q), STP, DHCP, DNS, etc. The concept of how a routing table is built is identical. The concept of how a packet is forwarded is also the same. Similarly, the concept of how a firewall filter works is unchanged. You only need to learn the different commands to implement them.

2. Similar Command-Line Interface (CLI) Logic

If you are comfortable with the Cisco CLI, the MikroTik CLI will feel familiar, not foreign.

• Hierarchical Mode Structure: Like Cisco’s config terminal, MikroTik has a similar hierarchy. You navigate to a specific context (like /interface ethernet or /ip firewall) to configure related settings.
• Tab Completion and “?”: MikroTik uses the Tab key for auto-completion and the ? key for context-sensitive help, just like Cisco. This is a huge help for learning commands.
• Show Commands: The equivalent of Cisco’s show commands in MikroTik is print or monitor. For example:
  • show ip route (Cisco) becomes /ip route print (MikroTik).
  • show interfaces becomes /interface print.
• Configuration Principles: The idea of making a change is similar. Saving the configuration (copy run start in Cisco vs /system backup save in MikroTik) follows this principle.

3. Powerful GUI Management Tool: Winbox

This is where MikroTik can actually be easier than Cisco for certain tasks.

• Winbox is a lightweight, standalone application that connects directly to the router’s MAC or IP address. It provides a very intuitive and responsive graphical interface for almost every feature.
• Real-time Monitoring: It excels at showing real-time traffic, graphs, and logs. This method is often more visual and immediate than Cisco’s CLI.
• “Best of Both Worlds”: A network engineer can use the Cisco-like CLI for efficiency. They can also use the powerful GUI for visualization and quick changes. For someone new, the GUI can make complex concepts like firewall chains or queue trees much easier to understand.

Key Differences to Be Aware

While the concepts transfer, the commands are different. Here are the main differences a Cisco engineer will notice:

Summary: Why it’s “Easy” for a Cisco User

1. You Already Know the Hard Part: You understand IP routing, subnetting, VLANs, and protocols. Learning a new syntax is much easier than learning the concepts from scratch.
2. The CLI Feels Familiar: The hierarchical structure and use of ? and Tab make it easy to explore and find commands.
3. Winbox is a Great Aid: The GUI provides a fantastic safety net. It is a visual tool that Cisco’s CLI-only approach lacks for most devices.
4. The Logic is Transferable: The thought process of “I need to create a VLAN” is clear. You need to assign an IP and add a firewall rule. This process is identical. You just need to translate the steps into MikroTik’s language.

In conclusion: MikroTik isn’t “Cisco-made-easy.” It’s a different, powerful system. Both systems are built on the same foundational knowledge of networking. Therefore, a Cisco engineer can learn MikroTik’s syntax and unique tools very quickly. The underlying logic you’ve already mastered from Cisco does most of the heavy lifting.
