Configuring a FortiGate SSL VPN

Topology

When the user initiates a VPN connection with the FortiGate unit through the SSL VPN client, the FortiGate unit establishes a tunnel with the client and assigns the client a virtual IP address from a range of reserved addresses. The client uses the assigned IP address as its source address for the duration of the connection. After the tunnel has been established, the user can access the network behind the FortiGate unit.

Configuring the FortiGate unit to establish a tunnel with remote clients involves selecting tunnel-mode access in the user group settings and enabling the feature through SSL VPN configuration settings. The firewall policy and protection profiles on the FortiGate unit ensure that inbound traffic is screened and processed securely.

Tunnel-mode client requirements

The remote computer must be equipped with the following software:

Microsoft Windows 2000/XP/2003 or Vista (32 or 64-bit), MacOS X v10.3.9, v10.4 “Tiger”, v10.5 “Leopard”, or Linux Distributions RedHat/Fedora, Ubuntu/Debian, or Suse

Microsoft Internet Explorer 6.0 (or later) with ActiveX enabled, or Mozilla Foundation/Firefox (1.5 or later) with Java Platform enabled

Note: The browser requirements only apply if you use the tunnel mode client on Windows through the browser interface. You do not need a browser if you use the standalone tunnel client.

Note: The user account used to install the SSL VPN client on the remote computer must have administrator privileges.

Topology

In the most common Internet scenario, the remote client connects to an ISP that offers connections with dynamically assigned IP addresses. The ISP forwards packets from the remote client to the Internet, where they are routed to the public interface of the FortiGate unit.

At the FortiGate unit, you configure user groups and firewall policies to define the server applications and IP address range or network that remote clients will be able to access behind the FortiGate unit.

For example, Figure 1 shows a FortiGate gateway (FortiGate_1) to two private networks, Subnet_1 and Subnet_2.
