SSL VPN dropping connections

When a FortiGate unit has multiple internet connections, the SSLVPN client can connect to the SSLVPN web portal, but when attempting to click Connect to start tunnel mode SSLVPN, the tunnel will start up for a few seconds, then shut down.

This issue occurs when there are multiple interfaces connected to the Internet, for example, a dual wan configuration.

To resolve this issue, upgrade the FortiGate unit to at least 3.0 MR4 or higher. Use following commands in CLI to resolve the issue:

config vpn ssl settings

set route-source-interface enable

end

Note: This CLI command is only available in FortiOS 3.00 MR4 and higher.

In addition to its powerful security features, FortiOS v3.0 MR7 includes advanced reporting and logging capabilities. Users can generate detailed reports that highlight security events, traffic patterns, and performance metrics. This data not only improves visibility into network security but also assists in compliance with regulatory requirements.

Moreover, the platform's user-friendly interface enhances the overall management experience. Administrators can quickly configure settings, monitor activity, and respond to incidents effectively. With centralized management capabilities, FortiOS v3.0 MR7 allows organizations to manage multiple devices from a single console, simplifying operations and reducing administrative overhead.
