Combining WiFi and wired networks with a software switch

Facebooktwittergoogle_plusredditpinterestlinkedinFacebooktwittergoogle_plusredditpinterestlinkedin

Including mobile (WiFi) users on your office LAN can be more convenient than putting them on a separate wireless network. The Software Switch feature of your FortiGate is a simple way to do this.

Software Switches are only available if your FortiGate is in Interface mode. For more information, see Choosing your FortiGate’s switch mode.

1. Create the SSID

Go to WiFi Controller > WiFi Network > SSID and configure your wireless network.

Leave the IP address empty. This is allowed.

You can use any type of security/authentication. In this example, your users must be members of the employees group to access the network.

2. Combine the WiFi and wired interfaces

Go to System > Network > Interface. Edit the existing lan software switch interface or create a new one. 

Make sure your wired and WiFi interfaces are both included.

Make sure there is a DHCP Server configured. It will provide IP addresses to both WiFi and wired users.

Go to Policy & Objects > Policy > IPv4 and create a policy allowing all users on the software switch interface to connect to the Internet. policy
