Configuring a FortiGate SSL VPN Configuration overview

Configuration overview

Before you begin, install your choice of HTTP/HTTPS, telnet, SSH, FTP, SMB/CIFS, VNC, and/or RDP server applications on the internal network. As an alternative, these services may be accessed remotely through the Internet. All services must be running. Users must have individual user accounts to access the servers (these user accounts are not related to FortiGate user accounts or FortiGate user groups).

To configure FortiGate SSL VPN technology, you should follow these general steps:

1Enable SSL VPN connections and set the basic options needed to support SSL VPN configurations. See “Configuring SSL VPN settings” on page 36.

2To use X.509 security certificates for authentication purposes, load the signed server certificate, CA root certificate, and Certificate Revocation List (CRL) onto the FortiGate unit, and load the personal/group certificates onto the remote clients. For more information, see the FortiGate Certificate Management User Guide.

3Create one FortiGate user account for each remote client, and assign the users to SSL VPN type user groups. See “Configuring user accounts and SSL VPN user groups” on page 42.

4Configure the firewall policy and the remaining parameters needed to support the required mode of operation:

•For web-only mode operation, see “Configuring Web-only firewall policies” on page 46.

•For tunnel-mode operation, see “Configuring tunnel-mode firewall policies” on page 48.

5Define SSL VPN event-logging parameters. See “Configuring SSL VPN event- logging” on page 50.

6You can also monitor active SSL VPN sessions. See “Monitoring active SSL VPN sessions” on page 51.

Configuring the SSL VPN client

There are several configurations of SSL VPN applications available. The SSL VPN tunnel client application installs a network driver on the client machine that redirects all network traffic through the SSL VPN tunnel (it is necessary for the driver to be OS-specific).

SSL VPN web-mode works on all OSs and browsers. The tunnel mode client can be downloaded and installed from the browser interface on Windows platforms through ActiveX for IE, or Firefox plug-ins. If you prefer not to initiate the tunnel mode client function using a browser, standalone SSL VPN tunnel client applications are available for Windows, Linux, and MacOS (see Tunnel-mode client requirements for the specific versions that are supported). When a system configuration must involve more secure disposal of cached data, the SSL VPN Virtual Desktop should be used. (Windows XP only).
