Appendix B: Configuring the NetExtender
WAN Acceleration Client
This appendix provides configuration procedures for activating, installing, and enabling the
NetExtender WAN Acceleration Client (WXAC). The configuration procedures are split into two
parts: one for the Administrator enabling/allowing NetExtender WAN Acceleration Clients to
connect to the central site, and one for the client configuring the NetExtender WXAC on a
remote PC. Both of these configurations must be complete for the NetExtender WXAC to work.
This appendix contains the following sections:
• Overview on page 159
• Requirements / Prerequisites on page 159
• Deployment Considerations on page 159
• Enabling WXAC on the Central Site on page 160
• Configuring WXAC on a Remote PC on page 164
Overview
The NetExtender Client allows remote PCs to connect to the central site via a VPN connection,
the NetExtender WAN Acceleration Client (WXAC) is an addition to the NetExtender Client, and
accelerates traffic though the VPN connection. Using the NetExtender WXAC on a remote PC
means the traffic at the central site will pass through the central site's WXA appliance.
Requirements / Prerequisites
The NetExtender WXAC requires the following:
• A SonicOS NSA/TZ series appliance running SonicOS 5.9 firmware.
• A WXA series appliance running WXA 1.2 or higher firmware.
• The WXA series appliance is connected and configured to the managing NSA/TZ series
appliance.
• The TCP Acceleration service is enabled on the WXA appliance.
Deployment Considerations
Please consider the following when deploying the NetExtender WXAC:
• When a user tries to enable WXAC, while PPP software compression is on, a dialog pops
up and the user needs to choose whether to reconnect the SSL VPN session. But the user
doesn't need to enter the server information and credentials if he chooses to reconnect the
session.
• The NetExtender WXAC is supported on all NSA/TZ series appliances except the following:
– TZ 100 series
– TZ 105 series
– TZ 200 series
