How can you modify the security settings of a VPN tunnel created from a template in FortiGate?

Modifying the security settings of a VPN tunnel created from a template in FortiGate can effectively be accomplished through the VPN template options in the console. When a VPN is created using a template, it encapsulates specific security configurations and parameters that serve as a baseline for the tunnel settings. By accessing the template options, administrators can make adjustments to various security parameters such as encryption methods, authentication settings, and other relevant configurations.

This streamlined approach allows for consistent updates across multiple tunnels that may utilize the same template, ensuring that all tunnels adhere to the latest security policies without the need to individually modify each one. It also helps maintain operational efficiency and aligns with organization-wide security practices by allowing for centralized management of VPN security settings within the FortiGate administrative console.

In contrast, directly editing the firewall policy may not specifically alter the VPN settings as required, while contacting Fortinet support would not typically be necessary for such modifications, as they can be handled directly by the administrator. The command line interface could be used for further customization or advanced settings, but utilizing the console template options is a more straightforward method for modifying the relevant security configurations of the VPN tunnel.
