Configuring Site-to-Site VPN On MikroTik Routers Step-by-Step Guide

Hey there, friends. Today, we're going to talk about a nifty little topic - setting up a site-to-site IPSec VPN tunnel configuration on a MikrotikRouter with one side having DHCP address. Sounds technical, right? Don't worry, we'll break it down for you.

First things first, let's talk about what a site-to-site IPSec VPN tunnel configuration is. Essentially, it's a way to connect two different networks securely over the internet. Think of it like a virtual private network (VPN) that connects two different locations - one location might be your office, and the other might be a satellite office or remote worker's home.

So why might you need a site-to-site VPN tunnel configuration? Well, for one thing, it allows different locations and workers to access the same resources, like file servers or printers. It can also be used to secure communication between different networks and prevent unauthorized access. Essentially, it's a way to make sure that your network communication is private and secure.

Now, let's get into the nitty-gritty of setting up a site-to-site IPSec VPN tunnel configuration on a MikrotikRouter with one side having DHCP address. Here are the steps:

Step 1: Choose your IP addresses

First, you'll need to choose the IP addresses that you want to use for your VPN tunnel. You'll need an IP address for each end of the tunnel - one for the local side (your network) and one for the remote side (the network you're connecting to).

Got it? Good. Now, here's the catch - one side of the tunnel has a DHCP address. DHCP, or Dynamic Host Configuration Protocol, is a protocol that automatically assigns IP addresses to devices on your network. So, if one side of your VPN tunnel has a DHCP address, that means it's not a fixed IP address - it could change at any time.

So, to set up your VPN tunnel configuration, you'll need to use a tool called DNS. DNS, or Domain Name System, is a system that maps domain names (like google.com) to IP addresses. Essentially, it's a way to make sure that your network traffic is sent to the right place, even if the IP address changes.

Step 2: Configure your router

Once you've chosen your IP addresses and made sure that one side has a DHCP address, it's time to configure your router. Here are the steps:

1. Open up your router's web user interface and click on the "IP" tab.
2. Select the "IPsec" option from the left-hand menu.
3. Click on the "Peers" tab and then click the "+" button to add a new peer.
4. Fill out the following information:
• ID: The ID of the peer (usually the IP address of the remote network).
• Address: The IP address of the remote network.
• Auth Method: Choose the authentication method you want to use (e.g. PSK).
• Pre-Shared Key: Enter the pre-shared key you want to use to authenticate the VPN tunnel.
• Exchange Mode: Choose the exchange mode you want to use (e.g. main).
• ID Type: Choose the type of ID you want to use (e.g. IP address).
• NAT Traversal: Select the "enable" option.
• Generate Policy: Select the "require" option.
• Send Initial Contact: Select the "on" option.
5. Click on the "Proposals" tab and then click the "+" button to add a new proposal.
6. Fill out the following information:
• Group Name: The name of the group (e.g. VPN tunnel).
• Encryption Algorithm: Choose the encryption algorithm you want to use (e.g. AES256).
• Hash Algorithm: Choose the hash algorithm you want to use (e.g. SHA1).
• Diffie-Hellman Group: Choose the Diffie-Hellman group you want to use (e.g. group14).
• PFS Group: Choose the PFS group you want to use (e.g. group14).
• Proposal Check: Select the "obey" option.
7. Click on the "Policies" tab and then click the "+" button to add a new policy.
8. Fill out the following information:
• Sa Src Address: The IP address of the local network.
• Sa Dst Address: The IP address of the remote network.
• Tunnel: Select the "yes" option.
• Protocol: Choose the protocol you want to use (e.g. all).
• Action: Choose the action you want to take (e.g. encrypt).
• Level: Choose the level you want to use (e.g. require).
9. Click on the "Phase 2" tab and then click the "+" button to add a new phase 2 policy.
10. Fill out the following information:
• Src Address: The IP address of the local network.
• Dst Address: The IP address of the remote network.
• Protocol: Choose the protocol you want to use (e.g. all).
• Tunnel: Select the "yes" option.
• Action: Choose the action you want to take (e.g. encrypt).
• Level: Choose the level you want to use (e.g. require).
11. Save your changes.

Step 3: Test your VPN tunnel configuration

Once you've configured your router, it's time to test your VPN tunnel configuration. Here are the steps:

1. Go to a computer on the local network and open up a browser.
2. Type in the IP address of the remote network that you're trying to connect to.
3. If everything is set up correctly, you should be able to access resources on the remote network, like file servers or printers.

And there you have it - a site-to-site IPSec VPN tunnel configuration on a MikrotikRouter with one side having DHCP address. It might seem like a mouthful, but once you get the hang of it, it's a great way to keep your network communication private and secure. Plus, it's just a cool trick to show off to your tech-savvy friends.

Until next time, happy configuring!
