Configuring the Network Settings
You can implement transparent bridging with ZoneFlex through the use of L2TP (Layer
2 Tunnelling Protocol) tunnelling. By tunnelling traffic from a ZoneFlex AP to a
centralized data center, access controllers with policy enforcement software can apply
rules and services. In a typical WLAN implementation, these rules include a captive
portal to authenticate users’ credentials.
In the case of L2TP, the ZoneFlex AP functions as a remote bridge. As such, it forwards
traffic into PPP sessions over the L2TP tunnel. This implementation ensures that you
have complete visibility into MAC addresses of users, as individual Wi-Fi clients are
essentially placed (bridged) onto the ISP’s core network.
To configure L2TP tunnelling
1. Go to Configuration > Internet.
2. Under L2TP Connection, click Enable.
3. In L2TP Network Server IP Address, type the IP address of the L2TP network
server (LNS) to which the device will connect.
4. In Server Secret, type the L2TP tunnel password.
5. If your network requires PPP authentication, configure the following fields under
L2TP/PPP Authentication:
• Username: Type your appropriate PPP user name.
• Password: Type the password appropriate to the account.
• Password Confirmation: Re-enter the password.
6. Click Update Settings to save your settings.
As ZoneFlex devices support multiple wireless networks (SSIDs), you should define
which SSID should be tunneled and which should be locally bridged. You can
configure this on the VLAN page. For more information, refer to “Configuring VLAN
Settings” on page 75.
