Configuring interfaces
Network configuration
Changing an interface static IP address
Use the following procedure to change the static IP address of any FortiGate
interface:
1
Go to
System > Network > Interface
.
2
Select Modify
for the interface to change.
3
Change the IP address and Netmask as required.
The IP address of the interface must be on the same subnet as the network the
interface is connecting to.
Two interfaces cannot have the same IP address and cannot have IP addresses on
the same subnet.
4
Select OK to save your changes.
If you changed the IP address of the interface that you are connecting to manage the
FortiGate unit, you must reconnect to the web-based manager using the new interface
IP address.
Adding a secondary IP address to an interface
You can use the CLI to add a secondary IP address to any FortiGate interface. The
secondary IP address cannot be the same as the primary IP address but it can be on
the same subnet.
To add a secondary IP address from the CLI enter the command:
set system interface <intf_str> config secip <second_ip>
<netmask_ip>
You can also configure management access and add a ping server to the secondary
IP address.
set system interface <intf_str> config secallowaccess ping
https ssh snmp http telnet
set system interface <intf_str> config secgwdetect enable
Adding a ping server to an interface
Add a ping server to an interface if you want the FortiGate unit to confirm connectivity
with the next hop router on the network connected to the interface. Adding a ping
server is required for routing failover. See
“Adding destination-based routes to the
routing table” on page 143
.
1
Go to
System > Network > Interface
.
2
Select Modify
for the interface to which to add a Ping server.
3
Set Ping Server to the IP address of the next hop router on the network connected to
the interface.
4
Select Enable.
The FortiGate unit uses dead gateway detection to ping the Ping Server IP address to
make sure that the FortiGate unit can connect to the this IP address. To configure
dead gateway detection, see
“To modify the Dead Gateway Detection settings” on
page 159
.
