Fortinet 110C manual To set an interface to use PPPoE addressing, To configure DNS server settings

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.

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.
