Configure a Secure Connection to a Microsoft Windows Client Chapter 3
Communicate to the Module
via an RSLinx Driver If you communicate to the module through an RSLinx driver, you must use an
L2TP connection and the Ethernet devices (AB_ETH-1) driver.
Once the secure tunnel exists to the 1756-EN2TSC module, RSLinx software
uses the L2TP server IP addresses to communicate with the controller through
the 1756-EN2TSC module.
In the AB_ETH driver configuration, enter the L2TP server IP address (virtual
IP address) of the 1756-EN2TSC module to the Station Mapping dialog box.
IMPORTANT The Microsoft Windows client must use the module IP address specified (predetermined) on the
L2TP configuration tab for all communication to the module, including RSLinx and Studio 5000
connections. The original IP address for the module is not in the VPN tunnel and cannot be used.
