Use Vpn To Connectremote Windowsrnvista Clients To System I

摘要

One of the awesome features of System i and i5/OS is the large list of built-in security functions. Microsoft is also promoting increased security with Windows Vista. You can easily use the built-in security features of both systems to provide secure remote access to your work-from-home and mobile "road warrior" users.rnWe use three core Virtual Private Network (VPN) technologies to provide this secure remote access: Internet Key Exchange Protocol (IKE), IP Layer 3 Security Protocol (IPSec), and Layer 2 Tunneling Protocol (L2TP).rn1. IKE negotiates the encryption algorithms and keys based on the policy you specify. Your policy must be compatible with Windows Vista if you've used a VPN for Windows XP or Windows 2000 in the past.rn2. IPSec transfers the data encrypted at the IP layer.rn3. L2TP provides additional authentication and access control and lets your remote users appear to be part of your private network.
