| Description | This article describes that Port A and Port B seen in model FortiGate 60F/61F, 70F/71F, 80F/81F, and 90G/91G can be used as regular traffic ports. |
| Scope | Entry-level FortiGate. |
| Solution |
In earlier FortiGate models, there could be dedicated ports for DMZ or even HA (FortiGate 80E/81E). However, when upgrading such a model to a different or newer model, port index/numbering could change and DMZ or HA ports may no longer exist. In many models, there are ports called Port A and Port B as part of FortiLink.
These FortiLink Ports are pre-defined ports used to connect to FortiSwitch as a logical extension for the firewall. But if there is no plan to deploy FortiSwitch, Port A and Port B can be used as regular traffic ports (RJ45), for example, mapping DMZ port to Port A and HA port to Port B.
Modify the default setting and make Port A and Port B available to use. With the factory default settings, Port A and Port B are configured to be included in the FortiLink interface as seen below.

The following procedure/screenshot explains how to remove port A and port B from FortiLink. FortiLink if not used can also be deleted (not deleted in the screenshot below):
As can be seen above, Port A and Port B now show up as regular unused traffic ports.
Such info can also be seen in the FortiGate 60F/61F datasheet. |
