Enabling Vista IPSec

Introduction

Traditionally, IPSec has been used for remote connections, but this

feature has moved into the Local Area Network (LAN) to secure local

network traffic against eavesdropping.

Vista’s Next Generation TCP/IP stack provides APIs for accessing

brackets to allow advanced granularity to filter both inbound and outbound

traffic.This was not possible with Microsoft’s XP Operating system. In

addition, Vista’s security management now closely ties the Firewall and

IPSec features together by using a snap-in called Windows Firewall with

Advanced Security. The onboard encryption engine on the AT-2712FX/SC

and AT-2912T adapters allows off-loading of this task to the network

controller instead of the host CPU, thereby freeing the host CPU for other

important tasks. The off-loading feature is unique in the industry and

enables you to set tight security efficiently within your network at a minimal

cost.

Microsoft’s Technet website, www.technet.microsoft.com, offers several

technical publications as well as online seminars that describe Vista’s

advanced IPSec and Firewall features and their implementation. These

topics are beyond the scope of this chapter. Instead, Allied Telesis

recommends that you consult Technet for additional information.
