Configuring <strong>FortiGate</strong>_2<br />

The configuration for <strong>FortiGate</strong>_2 is very similar that of <strong>FortiGate</strong>_1. You must<br />

• configure the interfaces involved in the <strong>VPN</strong><br />

virtual <strong>IPSec</strong> interface for each one<br />

• define the phase 2 configuration for each of the four possible paths<br />

• configure routes for the four <strong>IPSec</strong> interfaces, assigning the appropriate<br />

• configure in<strong>com</strong>ing and outgoing firewall policies between the internal interface<br />

To configure the network interfaces<br />

1 Go to System > Network > Interface.<br />

2 Select the Edit icon for the Internal interface, enter the following information and<br />

then select OK:<br />
