VPN configuration procedures

The FortiGate VPN Guide uses a task-based approach to provide all of the procedures needed to create different types of VPN configurations. The guide contains the following chapters:

“Configuring IPSec VPNs” describes how to set up various IPSec VPN configurations.

“Configuring PPTP VPNs” describes how to configure a PPTP tunnel between a FortiGate unit and a PPTP client.

“Configuring L2TP VPNs” describes how to configure the FortiGate unit to operate as an L2TP network server.

“Monitoring and Testing VPN Tunnels” outlines some general monitoring and testing procedures for VPNs.

General high-level procedures are presented here. For details, see the FortiGate VPN

Guide.

IPSec configuration procedures

The following configuration procedures are common to all IPSec VPNs:

1Define the phase 1 parameters that the FortiGate unit needs to authenticate remote peers and establish a secure a connection. See “Phase 1” on page 246.

2Define the phase 2 parameters that the FortiGate unit needs to create a VPN tunnel with a remote peer. See “Phase 2” on page 250.

3Define source and destination addresses for the IP packets that are to be transported through the VPN tunnel, and create the firewall encryption policy, which defines the scope of permitted services between the IP source and destination addresses. See “Adding firewall policies for IPSec VPN tunnels” on page 266.

Note: Perform Steps 1 and 2 to have the FortiGate unit generate unique IPSec encryption and authentication keys automatically. In situations where a remote VPN peer requires a specific IPSec encryption and/or authentication key, you must configure the FortiGate unit to use manual keys instead of performing Steps 1 and 2. For more information, see “Manual key” on page 253.

Adding firewall policies for IPSec VPN tunnels

Firewall policies control all IP traffic passing between a source address and a destination address. A firewall encryption policy is needed to allow the transmission of encrypted packets, specify the permitted direction of VPN traffic, and select the VPN tunnel that will be subject to the policy. A single encryption policy is needed to control both inbound and outbound IP traffic through a VPN tunnel.

Before you define the policy, you must first specify the IP source and destination addresses.

To define an IP source address

1Go to Firewall > Address and select Create New.
