Configuring NAT mode

Initial PADT Timeout

Initial PPPoE Active Discovery Terminate (PADT) timeout in

 

seconds. Use this timeout to shut down the PPPoE session if it

 

is idle for this number of seconds. Your ISP must support

 

PADT. To disable the PADT timeout, set the value to 0.

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.

4Select OK.

5Repeat this procedure for each interface as required.

Note: If you change the IP address of the interface you are connecting to, you must connect through a web browser again using the new address. Browse to https:// followed by the new IP address of the interface. If the new IP address of the interface is on a different subnet, you may have to change the IP address of your computer to the same subnet.

Configure a DNS server

A DNS server is a service that converts symbolic node names to IP addresses. A domain name server (DNS server) implements the protocol. In simple terms, it acts as a phone book for the Internet. A DNS server matches domain names with the computer IP address. This enables you to use readable locations, such as fortinet.com when browsing the Internet.

DNS server IP addresses are typically provided by your internet service provider.

To configure DNS server settings

1Go to System > Network > Options.

2Enter the IP address of the primary DNS server.

3Enter the IP address of the secondary DNS server.

4Select Apply.

Adding a default route and gateway

A route provides the FortiGate unit with the information it needs to forward a packet to a particular destination. A static route causes packets to be forwarded to a destination other than the default gateway. You define static routes manually. Static routes control traffic exiting the FortiGate unit-you can specify through which interface the packet will leave and to which device the packet should be routed.

In the factory default configuration, entry number 1 in the Static Route list is associated with a destination address of 0.0.0.0/0.0.0.0, which means any/all destinations. This route is called the "static default route". If no other routes are present in the routing table and a packet needs to be forwarded beyond the FortiGate unit, the factory configured static default route causes the FortiGate unit to forward the packet to the default gateway.
