This document describes how to configure the Windows system to use IPSec VPN to connect to your office through the AR415S router.
When your staff want to connect to the office they simply use the VPN icon on their desktop to initiate the IPSec VPN connection.
Which products and releases does it apply to?
The following Allied Telesis routers are most suitable as VPN gateways because they have fast hardware encryption support and high performance:
zAR415S, AR44xS series, and AR450S
zAR750S and AR770S
The AR415S achieves up to 90 Mbps throughput with 3DES or AES encryption.
You can also use older routers as VPN gateways, but they will not have as high performance. The older routers depend on either the Encryption Mini Accelerator Card (EMAC) or the Encryption PCI Accelerator Card (EPAC) to perform encryption. They include:
zAR725, AR745, AR720 and AR740 routers
zAR410 series routers
zAR300 series routers
Finally, you can also use the Rapier 24 and Rapier 24i switches as VPN gateways, but this is usually not a recommended practice. Doing so means you will lose
Encryption algorithms such as 3DES and AES require a feature licence. This is included on some models. See your Allied Telesis representative for more information.
The configuration is supported on all AlliedWare versions since 2.3.1 and was tested using a PC running Microsoft Windows 2000 Professional, Service Pack 4.
