Description This article describes how to configure an SSL VPN with two separate SSL certificates.
Scope FortiGate configured with SSL VPN, using one SSL Certificate.
Solution

While it is not possible to define two different certificates under the SSL VPN settings, it is possible to configure an SSL VPN interface using a single certificate. The solution is to create a certificate with multiple SANs (subject alternative names). This can be done in a private CA, but this can be difficult to obtain for public signed certificates.

To separate SSL VPN configurations, consider also using VDOMs. These allow individual SSL VPN configurations for each VDOM in the FortiGate.
