Configuring NAT mode
22
To set an interface to use PPPoE addressing
config system interface
edit external
set mode pppoe
set username <name_str>
set password <psswrd>
set ipunnumbered <ip_address>
set disc-retry-timeout <integer_seconds>
set padt-retry-timeout <integer_seconds>
set distance <integer>
set defaultgw {enable | disable}
set dns-server-override {enable | disable}
end
The CLI lists the IP address, netmask, and other settings for each of the FortiGate
interfaces.
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
config system dns
set autosvr {enable | disable}
set primary <address_ip>
set secondary <address_ip>
end
Note if you set the autosvr to enable, you do not have to configure the primary
or secondary DNS server IP addresses.
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.
