U VPN pass-through
VPN technology (VPN=Virtual Private Network) is more and more frequently
in use to protect sensitive data. The BAT base station is able to route and
mask simultaneously the encrypted data between a VPN client of the WLAN
and another workstation of the cable-bound LAN. This “passing-through” of
VPN encrypted data is called in technical jargon “VPN pass-through”. Follow-
ing are provided:
D PPTP pass through
D IPsec pass through
Note: The BAT base stations support VPN pass-through function for multiple
stations within a wireless network.
U Wireless bridge between two Ethernet segments
With two base stations, two LANs can be connected via a radio link (point-to-
point mode). In this so-called bridge mode, all data is transferred automati-
cally to the remote network.
