MikroTik on Vultr Setup

Deploying MikroTik CHR (Cloud Hosted Router) on Vultr offers a flexible and powerful solution for networking needs.

Today, we are going to take a look at how to deploy MikroTik CHR on a Vultr server while making sure security measures are in place.

1: Deploy a Server in Rescue Mode

1. First, deploy a new Cloud Compute instance on Vultr.
2. Then, select the location with optimal performance via Vultr’s network-looking glass.
3. Next., choose the ISO Library tab, and then select SystemRescue x64 as the bootable Linux ISO.
4. Now, it is time to configure the server size with sufficient bandwidth.
5. At this point, enter a hostname and label, then click Deploy Now.
6. Once deployment is complete, proceed to the next step.

2: Write the CHR Image to the Disk

1. First, head to the MikroTik download page in a web browser.
2. Then, locate the latest Stable RAW CHR disk image.
3. Next, right-click the floppy disk icon to copy the download URL.
4. At this point, we have to access the server’s information page on the Vultr portal and connect to the web console.
5. Now, we can download the CHR image to the server with the `wget` command.
6. Then, unzip the downloaded file and write the MikroTik CHR image to the server’s disk with the `dd` command.

3: Connect to MikroTik CHR

1. To begin with, head to the server’s settings page on Vultr.
2. Then, go to the Custom ISO menu and click Remove ISO. This will push the server to reboot.
3. Next, we have to connect to the web console and log in as an admin with no password.
4. Now, view the software license and set a strong password.
5. Then, close the web console and open a terminal on the local computer.
6. At this point, we have to SSH as admin to the server’s IP address and enter the strong password.
7. Now, create a new administrator account, remove the default “admin” user, and disable unnecessary services.
8. Then, change the SSH port for added security.
9. After that, reconnect to the server on the new port with the new credentials.

Security Measures after VM is Running

1. To begin with, SSH into the admin user on the new VM, change the password and ensure no unauthorized access.
2. Then, monitor SSH service for about 30-45 seconds after the VM shows “Running” before connecting.

Furthermore, we can boost SSH Security with these steps:

1. Disable unnecessary services except SSH using `/ip service disable`.
2. Change the SSH port to a custom value (e.g., 2299) using `/ip service set`.
3. Set stronger cryptography and host key size for SSH using `/ip ssh set`.
4. Regenerate the SSH host key and reboot the CHR.

By following these steps, we can deploy MikroTik CHR on Vultr with enhanced security measures.
