Mikrotik IKEv2 Setup Guide (Updated)

Reza Poudineh

These days, the use of the IKEV2 encryption protocol to set up a VPN between two computers, two sites, and a remote office branch has increased. Because the IKEV2 protocol is relatively new and has very good capabilities for building a virtual private network and sending and receiving information securely and encrypted.

The easiest way to set up an IKEV2 server is to use Mikrotik routers. Along with Winbox software and RouterOS operating system, Mikrotik routers give you many features in terms of VPN, firewall, and proxy server, and you can easily install and set up an SSH or web server and Telnet on them, and a local access license for each user. gave

Today, most of network engineers and professionals started using Mikrotik hardware and software to meet their needs, such as routing in the network and setting up all kinds of servers, including web servers, VPN servers, proxy servers, file servers, firewalls, etc..

If you are unfamiliar with these concepts and are interested in taking computer network training, We suggest you visit the following site to learn these concepts in a simple and practical language.

Mikrotik servers give you the highest stability and security and have high boot speed and a series of automatic processes to get things done. These servers can be installed in a few minutes, and a series of commands can be given to it so that these tasks can be done with high speed and stability without the need to log in multiple times and in a row or restart processes.

Setting up and setting up Mikrotik servers is also simple, and most of the time, you can copy these settings from one system to another. For this reason, in recent years, many businesses or network professionals have been interested in setting up a VPN with Mikrotik servers, and the relatively new IKEV2 VPN protocol has shone brightly. In this article, we first want to have a look at some concepts and protocols and then check the installation steps of the IKEV2 protocol on Mikrotik.

Familiarity with Mikrotik, Mikrotik router, Winbox, and RouterOS

If you have been in the world of network and security and Internet hardware, You have probably heard and seen these expressions. Some say Mikrotik is hardware, and others consider Mikrotik an operating system and software. One article talks about the Mikrotik server, and another article says Mikrotik router or network settings in the Mikrotik software!

We must say that almost all these terms and concepts are correct. Initially, in 1996, two MIT students from “Latvia” in Eastern Europe developed and marketed the MicroTik operating system. This operating system was based on the Linux kernel, but its biggest advantage was the ability to install on ordinary PCs based on Microsoft Windows.

What are IKE and IKEv2 protocols?

Internet Key Exchange or IKE is an IPSec-based tunneling protocol that provides a secure VPN communication channel and defines automatic authentication and negotiation for IPSec SAs in a secure manner.

The first version of this VPN protocol (IKEv1) was introduced in 1998, and the second version (IKEv2) was released 7 years later.

If you want to get acquainted with various types of secure protocols, we have a thoroughly professional tutorial for you, which we have provided a link to you.

Features of the IKEv2 protocol

Why use IKEv2:

Security: IKEv2 uses a server authentication certificate, meaning that no action will be taken until the requester’s identity is known. This feature will prevent DDOS attacks.

Speed: Complex architecture and an efficient IKEv2 messaging system can improve performance. In addition, its connection speed is significantly faster, especially due to built-in NAT traversal, which significantly speeds up the passage of firewalls and connection establishment.

Pros of IKEv2 protocol

Disadvantages of the IKEv2 protocol

Perhaps the only negative point of this protocol is the use of UDP port 500, which will block some firewalls.

Mikrotik IKEv2 Setup Guide

Modern operating systems (such as Windows 7 and newer) support the IKEv2 standard. Internet Key Exchange (IKE or IKEv2) is a protocol that establishes a security association within the IPsec protocol suite. Compared to IKE version 1, IKEv2 includes improvements such as support for Mobility via MOBIKE standard and greater reliability. Mikrotik IKEv2 setup allows you to manage anonymous and secure internet traffic of devices connected to your router and unblock geo-restricted content. This article will examine how to set up ikev2 in Macrotik.

Advantages of setting up ikev2 on Mikrotik

The main performance advantage of IKEv2 over L2TP/IPsec VPNs is that L2TP assigns only one source IP per client, whereas IKEv2 has no restrictions. If, for example, three Windows laptops connected to the same Internet connection point (WiFi hotel or hotspot) are trying to connect to the company’s VPN, only the last connected device will succeed. It means just a laptop. However, this problem can be solved using one mobile hotspot for each laptop, but the source IP will change. Also, this option is not always available.

IKEv2 VPNs don’t have this problem with L2TP VPNs, so you can connect as many clients as you want to the endpoint. IKEv2 is much more difficult to configure for the first time than L2TP/IPsec and even more difficult for first-time OSX users.

Mikrotik’s 6.41 release channel has an issue that results in a local issuer certificate invalidation error. Sometimes IKEv2 connects well with exactly one code. However, when using version 6.41, in many cases, you will encounter the error “local issuer certificate depth 0” in the Mikrotik Log in the IPsec section. Use the BugFix/Stable channel (currently 6.393) to fix this issue.

Licensing management

The MikroTik router is becoming a licensing authority that can sign the TLS server certificate and the licenses for the connected devices. This means connected computers are authenticated by the device, not by username and password. You must configure Radius authentication if you prefer to have the username and password in the Machine Permissions header. To issue a license, you can follow the example code below:

The default key expiration is 365 days (1 year), so set it to 3650 (10 years) to avoid validity issues. Set the VPN provider’s DNS address as the common name. For example, vpn.yourdomain.com. In this example, CA-Crl-Host is set as the LAN IP address of the device. In this way, we create a licensing management center that allows the issuance of licenses and certificates.

Configuring ikev2 settings in Mikrotik

Mikrotik’s ikev2 setup tutorial aims to have clients connect their VPN to a subnet to obtain their IP address from a DHCP server on the main LAN. Also, it allows you to manage the subnet of VPN clients with custom rules if needed, which is very useful for access control or traffic shaping.

How to setup ikev2 in MIkrotik

As mentioned, ikev2 is the protocol used to set up a security association in the IPsec protocol suite. Setting up ikev2 on Mikrotik can generally be summarized in three steps:
