Some scenarios require Wi-Fi traffic from branch offices to be directed via the central site. Operating a WLAN controller Controller allows this to be achieved with a WLC tunnel-Tunnel. Without a WLAN controllerController, it is possible to transmit the Wi-Fi data traffic to a LANCOM router via an L2TP tunnel, and break-out the data there.
...
- The router is configured with the network INTRANET with the IP address range 172.16.0.0/24 and the IP address 172.16.0.254.
- An L2TPv3 tunnel has to be created on the router to transmit the Wi-Fi traffic.
- An additional network must be created for the Wi-Fi traffic. This is assigned the name L2TP-Network with the IP address range 192.168.1.0/24 and the IP address 192.168.1.254.
- The router acts as a gateway in this network.
- The DHCP server is activated for this network, so that Wi-Fi end devices can obtain an IP address.
...
- Network name: Enter a descriptive name for the L2TP network (in this example L2TP-NETWORK).
- IP address: Enter an IP address from an as yet unused IP network (in this example 192.168.1.254).
- Netmask: Enter the corresponding subnet mask.
- Interface assignment: From the drop-down menu, select the bridge group created in step 1.10 (in this case BRG-2).
...
- Tunnel-ID: Enter a descriptive name for the L2TP tunnel (in this example L2TP-SSID).
- IP-Address: Enter the IP address of the LANCOM router where it should be reached from the access point (in this example 172.16.0.254).
- Hostname: Enter a descriptive name for the access point (in this example AP1).
- Password: Enter the password used in step 1.3. This is used for authentication with the central router.
