Easily Modify VPN Tunnel Security Settings in FortiGate

When it comes to enhancing the security of a VPN tunnel created from a template in FortiGate, it might seem like a daunting task at first. However, by breaking down the steps, we can see it’s more manageable than it appears. Security settings in VPN tunnels are crucial to ensure data integrity and confidentiality, which is why understanding how to tweak them to fit specific needs is essential. This guide walks you through the process, making it easy to implement changes securely and efficiently.

Understanding FortiGate VPN Templates

What is a VPN Template?

A VPN template in FortiGate serves as a blueprint for setting up VPN tunnels across multiple devices. By using templates, network administrators can ensure uniform configuration, which simplifies management and troubleshooting. ForestVPN users, for instance, appreciate the ease of setting up secure connections without diving into complex configurations every time.

Why Modify Security Settings?

You might wonder, why bother modifying security settings of a template? Well, different applications and data sensitivities require varying levels of security. By customizing these settings, you optimize the tunnel’s performance and security, adhering to your organization’s specific requirements.

Steps to Modify Security Settings

Step 1: Access the VPN Template

1. Navigate to the FortiGate dashboard.
2. Select Device Manager and locate your desired VPN template under Provisioning Templates.

Step 2: Update IPsec Settings

• Encryption and Authentication: Choose stronger algorithms like AES256 and SHA256 for enhanced security.
• Diffie-Hellman Groups: Opt for higher group numbers (e.g., Group 14 or above) to improve security during the key exchange process.

Step 3: Configure Phase 1 and Phase 2

Phase 1:

• Set the IKE version to 2 for better security features.
• Enable NAT traversal if a NAT device exists between the FortiGate and the remote peer.

Phase 2:

• Enable Perfect Forward Secrecy (PFS) to ensure session keys are not compromised if a private key is leaked.
• Adjust Key Lifetime settings to shorter durations to reduce the window of opportunity for potential attackers.

Example Configuration Table

Setting	Recommended Value
Encryption	AES256
Authentication	SHA256
DH Group	14
IKE Version	2
PFS	Enabled
Key Lifetime (s)	3600

Step 4: Assign and Apply Changes

• Once modifications are made, assign the updated template to the relevant devices.
• Use the Install Wizard to push changes, ensuring all settings are correctly applied.

Step 5: Verify Tunnel Status

• Go to VPN Manager > Monitor to check the tunnel status.
• Ensure that tunnels are up and running, and troubleshoot any issues if necessary.
