Summary

A virtual private network (VPN) is the extension of a private network that encompasses links across shared or public networks such as the Internet. You can send data between two computers by using a VPN across a shared or public network in a manner that emulates a point-to-point private link. VPN connections allow users who work at home or travel to obtain a remote access connection to an organization server by using the infrastructure that is provided by a public network, such as the Internet.

This article discusses about how to configure ISA Server for VPN in different scenarios.

  1. You enable VPN access and set VPN properties in the ISA Server Management MMC snap-in.
  2. Create a site-to-site network object to represent the remote site.
  3. Configure the ISA or Microsoft Forefront Threat Management Gateway, Medium Business Edition Server network rules to specify the way traffic flows between networks.
  4. Configure access rules for traffic inspection and filtering.

For remote site VPN connections, you can use ISA Server�s VPN quarantine capabilities to include the VPN clients on a quarantined VPN clients network until their compliance with corporate security requirements are verified. If the clients qualify after the verification process, the VPN clients are moved to the VPN clients network. The quarantined VPN clients network and the VPN clients network are subject to the ISA Server firewall access policy. This helps you control VPN client access to network resources.
