NAT/Route mode installation	Completing the configuration

Completing the configuration

Use the information in this section to complete the configuration of the FortiGate unit.

Configuring the DMZ interface

Use the following procedure to configure the DMZ interface:

1Log into the web-based manager.

2Go to System > Network > Interface.

3Choose the dmz interface and select Modify .

4Change the IP address and Netmask as required.

5Select Apply.

Configuring interfaces 1 to 4

Use the following procedure to configure the eight user-defined interfaces:

1Log into the web-based manager.

2Go to System > Network > Interface.

3Choose a user-defined interface and select Modify . Select from port1 to port4.

4Change the IP address and Netmask as required.

5Select Apply.

Setting the date and time

For effective scheduling and logging, the FortiGate system date and time must be accurate. You can either manually set the system date and time or configure the FortiGate unit to automatically keep its time correct by synchronizing with a Network Time Protocol (NTP) server.

For information about setting the FortiGate system date and time, see “Setting system date and time” on page 169.

Changing antivirus protection

To change how antivirus protection to protects users on your internal network from downloading a virus from the Internet:

1Go to Firewall > Policy > Internal->External.

2Select Edit to edit this policy.

3Select Anti-Virus & Web filter to enable antivirus protection for this policy.

4Select a different Content Profile to change how antivirus protection is applied for this policy.

For a description of each of the content profiles, see “Content profiles” on page 218.

5Select OK to save the changes.
