Introduction
Setting up a secure and reliable site-to-site VPN is crucial for businesses that need to connect multiple locations or remote offices. In this blog post, we will guide you through the step-by-step configuration of a Fortinet site-to-site VPN using IP examples.
Step 1: Determine the IP Addresses
The first step is to determine the IP addresses of the two Fortinet devices that will be used for the VPN connection. Let’s say we have Device A with an IP address of 192.168.1.1 and Device B with an IP address of 192.168.2.1.
Step 2: Configure Device A
Log in to Device A’s web-based management interface and navigate to the VPN settings. Create a new VPN tunnel and specify the following details:
- Tunnel Name: Enter a name for the VPN tunnel.
- Local IP: Set the local IP address to 192.168.1.1.
- Remote IP: Set the remote IP address to 192.168.2.1.
- Encryption Algorithm: Choose the desired encryption algorithm.
- Authentication Algorithm: Choose the desired authentication algorithm.
Step 3: Configure Device B
Repeat the same steps on Device B. Log in to its web-based management interface, navigate to the VPN settings, and create a new VPN tunnel. Specify the following details:
- Tunnel Name: Enter a name for the VPN tunnel.
- Local IP: Set the local IP address to 192.168.2.1.
- Remote IP: Set the remote IP address to 192.168.1.1.
- Encryption Algorithm: Choose the same encryption algorithm as Device A.
- Authentication Algorithm: Choose the same authentication algorithm as Device A.
Step 4: Establish the VPN Connection
Once the VPN tunnels are configured on both devices, it’s time to establish the connection. On Device A, go to the VPN settings and click on the ‘Connect’ button for the VPN tunnel. Device A will initiate the connection and establish the VPN tunnel with Device B.
Step 5: Test the VPN Connection
To ensure that the VPN connection is working properly, you can perform a simple ping test. From a device connected to Device A’s network, ping an IP address on Device B’s network. If the ping is successful, it means that the VPN connection is up and running.
Conclusion
Configuring a Fortinet site-to-site VPN is a straightforward process that requires careful attention to detail. By following the step-by-step instructions provided in this blog post, you can easily set up a secure and reliable VPN connection between two Fortinet devices using IP examples.
