IPv6

From an administrative point of view IPv6 works almost the same as IPv4 in FortiOS. The primary difference is the use of IPv6 format for addresses. See IPv6 overview for more information.

By default, the IPv6 settings are not displayed in the GUI.

To enable IPv6 in the GUI:

1. Go to System > Feature Visibility.

2. Under Core Features, enable IPv6.

3. Click Apply.

Once enabled, you will be able to use IPv6 addresses as well as the IPv4 addressing for the following FortiGate firewall features which are not limited to:

• Interfaces

• DHCP Server

• DHCP Relay

• DNS

• Static Routes

• Firewall Policy

• NAT

• Addresses

• Virtual IPs

• IP Pools

• IPsec VPN

• GRE over IPsec
