Introduction

The configuration of an IPSec VPN with callback (IP address in the B/D-channel) with a bintec RS232bw™ is described in the following chapters.

Configuration is performed with the GUI™ (Graphical User Interface).

The branch office of a company is to be connected to the head office over an IPSec tunnel. An xDSL connection is available for the Internet connection in both the branch office and head office. Both devices receive their IP address dynamically from the Internet Service Provider (ISP). To set up the IPSec tunnel in both directions, the IP address should be transferred to the partner over ISDN.
