Configuring NAT mode

Configuring

For an initial configuration, you must edit the factory configured static default route 
to specify a different default gateway for the FortiGate unit. This will enable the 
flow of data through the FortiGate unit.

For details on adding additional static routes, see the 

FortiGate Administration 

Guide

.

To modify the default gateway

1

Go to 

Router > Static

.

2

Select Edit for the default route

3

In the Gateway field, type the IP address of the next-hop router where outbound 
traffic is directed.

4

If the FortiGate unit reaches the next-hop router through a different interface 
(compared to the interface that is currently selected in the Device field), select the 
name of the interface from the Device field.

5

Select OK.

Adding firewall policies

Firewall policies enable traffic to flow through the FortiGate interfaces. Firewall 
policies define how the FortiGate unit processes the packets in a communication 
session. You can configure the firewall policies to allow only specific traffic, users 
and specific times when traffic is allowed.

For the initial installation, a single firewall policy that enables all traffic through will 
enable you to verify your configuration is working. On lower-end units such a 
default firewall policy is already in place. For the higher end FortiGate units, you 
will need to add a firewall policy.

The following steps add two policies that allows all traffic through the FortiGate 
unit, to enable you to continue testing the configuration on the network.

To add an outgoing traffic firewall policy

1

Go to 

Firewall > Policy

.

2

Select Create New.

3

Set the following and select OK.

To add an incoming traffic firewall policy
