LAN port options

Some FortiAP models have one or more LAN interfaces that can provide wired network access. LAN ports can be

• bridged to the incoming WAN interface
• bridged to one of the WiFi SSIDs that the FortiAP unit carries
• connected by NAT to the incoming WAN interface

There are some differences among FortiAP models.

Models like 11C and 14C have one port labeled WAN and one or more ports labeled LAN. By default, the LAN ports are offline. You can configure LAN port operation in the FortiAP Profile in the GUI (Wireless Controller > FortiAP Profiles) or in the CLI (config wireless-controller wtp-profile, config lan subcommand).

Models like 320C, 320B, 112D, and 112B have two ports, labeled LAN1 and LAN2. LAN1 acts as a WAN port connecting the FortiAP to a FortiGate or FortiCloud. By default, LAN2 is bridged to LAN1. Other modes of LAN2 operation must be enabled in the CLI:

config wireless-controller wtp-profile

edit <profile_name>

set wan-port-mode wan-lan

end

By default wan-port-mode is set to wan-only.

When wan-port-mode is set to wan-lan, LAN2 Port options are available in the GUI and the CLI the same as the other FortiAP models that have labeled WAN and LAN ports.

Bridging a LAN port with an SSID

Bridging a LAN port with a FortiAP SSID combines traffic from both sources to provide a single broadcast domain for wired and wireless users.

In this configuration

• The IP addresses for LAN clients come from the DHCP server that serves the wireless clients.
• Traffic from LAN clients is bridged to the SSID’s VLAN. Dynamic VLAN assignment for hosts on the LAN port is not supported.
• Wireless and LAN clients are on the same network and can communicate locally, via the FortiAP.
• Any host connected to the LAN port will be taken as authenticated. RADIUS MAC authentication for hosts on the LAN port is not supported.

For configuration instructions, see LAN port options.

Bridging a LAN port with the WAN port

Bridging a LAN port with the WAN port enables the FortiAP unit to be used as a hub which is also an access point.

In this configuration

• The IP addresses for LAN clients come from the WAN directly and will typically be in the same range as the AP itself.
• All LAN client traffic is bridged directly to the WAN interface.
• Communication between wireless and LAN clients can only occur if a policy on the FortiGate unit allows it.

For configuration instructions, see LAN port options.

Configuring FortiAP LAN ports

You can configure FortiAP LAN ports for APs in a FortiAP Profile. A profile applies to APs that are the same model and share the same configuration. If you have multiple models or different configurations, you might need to create several FortiAP Profiles. For an individual AP, it is also possible to override the profile settings.

To configure FortiAP LAN ports - GUI

1. If your FortiAP unit has LAN ports, but no port labeled WAN (models 320C, 320B, 112D, and 112B for example), enable LAN port options in the CLI:

   config wireless-controller wtp-profile

   edit <profile_name>

   set wan-port-mode wan-lan

   end

2. Go to WiFi & Switch Controller > FortiAP Profiles.
3. Edit the default profile for your FortiAP model or select Create New.
4. If you are creating a new profile, enter a Name and select the correct Platform (model).
5. Select SSIDs.
6. In the LAN Port section, set Mode to Bridge to and select an SSID or WAN Port as needed.

   On some models with multiple LAN ports, you can set Mode to Custom and configure the LAN ports individually. Enable each port that you want to use and select an SSID or WAN Port as needed.
   

7. Select OK.

Be sure to select this profile when you authorize your FortiAP units.

To configure FortiAP LAN ports - CLI

In this example, the default FortiAP-11C profile is configured to bridge the LAN port to the office SSID.

config wireless-controller wtp-profile

edit FAP11C-default

config lan

set port-mode bridge-to-ssid

set port-ssid office

end

end

end

In this example, the default FortiAP-28C profile is configured to bridge LAN port1 to the office SSID and to bridge the other LAN ports to the WAN port.

config wireless-controller wtp-profile

edit FAP28C-default

config lan

set port1-mode bridge-to-ssid

set port1-ssid office

set port2-mode bridge-to-wan

set port3-mode bridge-to-wan

set port4-mode bridge-to-wan

set port5-mode bridge-to-wan

set port6-mode bridge-to-wan

set port7-mode bridge-to-wan

set port8-mode bridge-to-wan

end

end

In this example, the default FortiAP-320C profile is configured to bridge the LAN port to the office SSID.

config wireless-controller wtp-profile

edit FAP320C-default

set wan-port-mode wan-lan

config lan

set port-mode bridge-to-ssid

set port-ssid office

end

end

end

To configure FortiAP unit LAN ports as a FortiAP Profile override - GUI

1. Go to WiFi & Switch Controller > Managed FortiAPs.
   
2. Select the FortiAP unit from the list and select Edit.
3. Select the FortiAP Profile, if this has not already been done.
4. In the LAN Port section, select Override.
   The options for Mode are shown.
5. Set Mode to Bridge to and select an SSID or WAN Port, or NAT to WAN as needed.
   On some models with multiple LAN ports, you can set Mode to Custom and configure the LAN ports individually. Enable and configure each port that you want to use.
6. Select OK.

To configure FortiAP unit LAN ports as a FortiAP Profile override - CLI

In this example, a FortiAP unit’s configuration overrides the FortiAP Profile to bridge the LAN port to the office SSID.

config wireless-controller wtp

edit FP320C3X14020000

set wtp-profile FAP320C-default

set override-wan-port-mode enable

set wan-port-mode wan-lan

set override-lan enable

config lan

set port-mode bridge-to-ssid

set port-ssid office

end

end
