Function

The bintec router (e. g. bintec RS123™) serves, at the same time, as a gateway, firewall, WLAN controller and HotSpot gateway. The access points provide SSIDs which are each tagged with a separate VLAN. The router uses the tagging to separate the two traffic flows and provides them internally to two virtual ports.

The router provides three DHCP pools. One for the access points (192.168.100.10 to 192.168.100.110), this is automatically created by the wireless LAN controller wizard. When doing so, the wireless LAN controller wizard automatically includes the configuring of the DHCP option 138. That is the WLAN controller address which the access points require to communicate with the WLAN controller. The other two DHCP pools are created manually and are used, respectively, for the SSIDs employees and SSIDs guests .

	Note
	In small WLAN installations of up to 6 access points, a bintec W2003ac™ can also be used as a WLAN controller. This cannot be done here because the device also has to take on the HotSpot gateway functionality at the same time. However, to do this, router functions are required which are deactivated in the bintec W2003ac™ if it is working as a WLAN controller.
