Network Interconnection with IP Tunnel - MIKROTIK TUTORIAL [ENG SUB]

Summary

In this video, the MikroTik Indonesia YouTube channel demonstrates how to set up an IPIP tunnel to connect remote networks. The tutorial covers configuring two MikroTik hAP lite routers (Jawa and Bali) to create a secure tunnel over the internet, allowing local area networks (LANs) to communicate with each other despite being geographically distant. The video provides step-by-step instructions on setting up IP addresses, configuring the IPIP interface, and establishing static routing between the two routers, offering an alternative to direct cable connections or point-to-point wireless links.

Takeaways

• 😀 IP tunnels (also known as IPIP) allow for the creation of a tunnel-like path for data to travel over an existing network, often the Internet.
• 😀 IPIP is a simple and lightweight tunneling protocol that encapsulates IP packets into other IP packets, enabling communication between routers over long distances.
• 😀 IPIP tunnels are supported by various network devices, allowing MikroTik routers to connect with routers from different brands, or vice versa.
• 😀 The video demonstrates the configuration of two MikroTik routers (Jawa and Bali) connected over the internet using IPIP tunneling.
• 😀 The setup process includes configuring the public IP addresses of the routers and creating an IPIP interface to establish the tunnel.
• 😀 A /32 IP address is used in point-to-point configurations for IP tunnels, making the communication between routers appear as if they are directly connected.
• 😀 Static routing is necessary after establishing the IPIP tunnel to ensure that data from one network (e.g., Java) can reach the other network (e.g., Bali) through the tunnel.
• 😀 Basic configuration steps are shown for both routers, including setting up local and remote IP addresses, creating IP tunnel interfaces, and assigning IP addresses to the tunnel.
• 😀 Once the IP tunnel is configured, the two routers can communicate through the tunnel, allowing devices on both sides (e.g., PCs, laptops) to ping and share data.
• 😀 The tunnel’s performance is tested using the ping command and traceroute, demonstrating that the data packets successfully pass through the tunnel and reach the destination router.

Q & A

What is the purpose of using an IP tunnel like IPIP in networking?

An IP tunnel, such as IPIP, creates a virtual connection between two networks over the internet, allowing devices on different local area networks (LANs) to communicate as if they were directly connected, even if they are geographically far apart.

How does the IPIP tunneling protocol work?

IPIP works by encapsulating IP packets inside another IP packet, thus creating a tunnel. It adds 20-40 bytes of overhead to each packet, which allows the data to travel securely over the internet between two routers.

What are the key advantages of using IPIP tunneling over other protocols?

IPIP is lightweight and simple to implement, with minimal overhead. It is also cross-platform, meaning it can be used to connect MikroTik routers with devices from other manufacturers.

What is the role of static routing in the IPIP tunnel setup?

Static routing is used to direct traffic from one network to another through the IPIP tunnel. By configuring static routes on both ends of the tunnel, you can ensure that packets destined for a remote network are sent through the tunnel.

In the video, what configuration step is performed first on the Jawa Router?

The first configuration step on the Jawa Router involves checking and setting the IP addresses for the interfaces: ether1 for the internet connection and ether4 for the local network. After that, the IPIP tunnel is created.

How do you ensure that the local and remote IP addresses in the IPIP tunnel are correctly configured?

The local IP address should be the public IP of the router itself, while the remote IP address should be the public IP of the opposite router. In the case of the Jawa Router, the local address is 192.168.76.183, and the remote address is 192.168.73.202 (the public IP of the Bali Router).

Why is it important to assign a /32 subnet mask to the tunnel IP addresses?

A /32 subnet mask is used in point-to-point connections like an IPIP tunnel to ensure that the two tunnel endpoints communicate directly with each other without defining a range of IP addresses. This makes it a unique connection between the two routers.

How can you verify that the IPIP tunnel is functioning correctly?

Once the tunnel is configured, you can check if it is running by looking for the 'R' flag in the interface status. Additionally, performing a ping test between the two routers or performing a traceroute can help confirm that the tunnel is properly established.

What troubleshooting step is mentioned for verifying connectivity between devices in different locations?

To verify connectivity, a ping test is performed from a laptop connected to the Jawa Router to a laptop connected to the Bali Router. If the ping is successful, it confirms that the devices can communicate through the IPIP tunnel.

What is the significance of using Winbox in this tutorial?

Winbox is used in this tutorial as a graphical interface for managing MikroTik routers. It simplifies the configuration process by providing a user-friendly environment to set up the tunnel and static routing without needing to use command-line interface commands.
