MikroTik IKEv2/IPSec PSK RSA Configure: A Comprehensive Guide
MikroTik is a popular network infrastructure provider that offers a range of hardware and software solutions for small to large businesses. One of the key features of MikroTik's RouterOS is its support for various VPN protocols, including IKEv2/IPSec. In this article, we will guide you through the process of configuring IKEv2/IPSec on your MikroTik router using pre-shared key (PSK) and RSA encryption.
What is IKEv2/IPSec?
IKEv2 (Internet Key Exchange version 2) is a VPN protocol used to establish a secure connection between two devices over the internet. IPSec (Internet Protocol Security) is a suite of protocols used to secure IP communications by authenticating and encrypting each IP packet. IKEv2/IPSec is a combination of these two protocols, providing a highly secure and reliable VPN solution for organizations of all sizes.
IKEv2/IPSec with PSK and RSA Encryption
MikroTik routers support IKEv2/IPSec with PSK and RSA encryption. PSK is a shared secret key that is used to authenticate the connection between the two devices. RSA encryption is a public-key encryption algorithm that uses two keys, a public key and a private key, to encrypt and decrypt data.
Configuring IKEv2/IPSec with PSK and RSA on your MikroTik router involves the following steps:
Create the CA and Server Certificates
The first step is to create the Certificate Authority (CA) and server certificates. These certificates are used to authenticate the devices during the VPN connection. To create the CA and server certificates, follow these steps:
Log in to your MikroTik router and navigate to System > Certificates.
Click on the "Create Certificate" button and select "CA Certificate" from the drop-down menu.
Enter the CA name and select the "CA" checkbox.
Click on the "Create Certificate" button to generate the CA certificate.
Next, create the server certificate by following the same steps as above, but selecting "Server Certificate" instead of "CA Certificate". Enter the server name and select the "Server" checkbox. Once you have created both the CA and server certificates, download them to your local machine.
Create the IPSec Proposal
The next step is to create the IPSec proposal, which defines the encryption and authentication settings for the IPSec tunnel. To create the IPSec proposal, follow these steps:
Log in to your MikroTik router and navigate to IP > IPSec > Proposals.
Click on the "Add New" button to create a new proposal.
Enter a name for the proposal and select the encryption and authentication algorithms. For PSK authentication, select "pre-shared-key" from the "Authentication Algorithm" drop-down menu.
Click on the "OK" button to create the IPSec proposal.
Create the IPSec Policy
The IPSec policy defines the traffic that will be encrypted and sent over the IPSec tunnel. To create the IPSec policy, follow these steps:
Log in to your MikroTik router and navigate to IP > IPSec > Policies.
Click on the "Add New" button to create a new policy.
Enter a name for the policy and select the "Src. Address" and "Dst. Address" for the traffic that will be encrypted.
Select the IPSec proposal that you created in step 2 from the "Proposal" drop-down menu.
Click on the "OK" button to create the IPSec policy.
