Configuring NAT mode

Configuring NAT mode involves defining interface addresses and default routes, and simple firewall policies. You can use the web-based manager or the CLI to configure the FortiGate unit in NAT/Route mode.

Using the web-based manager

After connecting to the web-based manager, you can use the following procedures to complete the basic configuration of the FortiGate unit. Ensure you read the section “Connecting to the web-based manager” on page 16 before beginning.

Configure the interfaces

When shipped, the FortiGate unit has a default address of 192.168.1.99 and a netmask of 255.255.255.0. for either the Port 1 or Internal interface. You need to configure this and other ports for use on your network.

To configure interfaces

1Go to System > Network > Interface.

2Select the edit icon for an interface.

3Set the Addressing Mode for the interface.

For Manual addressing, enter the IP address and netmask for the interface.

For DHCP addressing, select DHCP and complete the following:

Distance

Enter the administrative distance, between 1 and 255 for the

 

default gateway retrieved from the DHCP server. The

 

administrative distance specifies the relative priority of a route

 

when there are multiple routes to the same destination. A

 

lower administrative distance indicates a more preferred route.

Retrieve default gateway from server

Override internal DNS

Enable to retrieve a default gateway IP address from the DHCP server. The default gateway is added to the static routing table.

Enable to use the DNS addresses retrieved from the DHCP server instead of the DNS server IP addresses on the DNS page on System > Network > Options. On FortiGate-100 units and lower, you should also enable Obtain DNS server address automatically in System > Network > Options.

For PPPoE addressing, select PPPoE, and complete the following:

Username

Enter the username for the PPPoE server. This may have

 

been provided by your ISP.

Password

Enter the password for the PPPoE server for the above user

 

name.

Unnumbered

Specify the IP address for the interface. If your ISP has

 

assigned you a block of IP addresses, use one of these IP

 

addresses. Alternatively, you can use, or borrow, the IP

 

address of a configured interface on the router. You may need

 

to do this to minimize the number of unique IP addresses

 

within your network.

 

If you are borrowing an IP address remember the interface

 

must be enabled, or up to function correctly.

Initial Disc Timeout

Initial discovery timeout in seconds. The time to wait before

 

starting to retry a PPPoE discovery. To disable the discovery

 

timeout, set the value to 0.
