config system dns
set primary <address_ip>
set secondary <address_ip>
end
Example
config system dns
set primary 293.44.75.21
set secondary 293.44.75.22
end
Adding a default route
Add a default route to configure where the FortiGate unit sends traffic that should
be sent to an external network (usually the Internet). Adding the default route also
defines which interface is connected to an external network. The default route is
not required if the interface connected to the external network is configured using
DHCP or PPPoE.
To add a default route
Set the default route to the Default Gateway IP address. Enter:
config router static
edit <seq_num>
set dst <class_ip&net_netmask>
set gateway <gateway_IP>
set device <interface>
end
Verify the connection
To verify the connection, try the following:
• ping the FortiGate unit
• browse to the web-based manager GUI
• retrieve or send email from your email account
If you cannot browse to the web site or retrieve/send email from your account,
review the previous steps to ensure all information was entered correctly and try
again.
You are now finished the initial configuration of the FortiGate unit.
Example
If the default gateway IP is 10.10.1.2 and this gateway is connected to the
external interface:
config router static
edit 1
set dst 0.0.0.0 0.0.0.0
set gateway 10.10.1.2
set device external
end
