The gateway links a controller with secure targets or with targets connected through an SNA backbone. The gateway always requires that you install a LAN directory on a workstation-any workstation-on the same LAN.

The gateway connects to all targets using the NetBIOS communication protocol. Therefore, install the gateway only in those parts of your network that use NetBIOS.

The gateway supports more than one session at a time so you probably need one gateway per logical LAN. To connect to secure targets, the gateway must be secure as well.
