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

Go to Router > Static.

Select Edit for the default route

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

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.

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

Select Create New.
