One ISA firewall feature that doesn’t get the attention it deserves is the VPN remote access server component. The ISA firewall’s VPN server can provide an unusually high level of security for your remote access VPN connections because it applies the same strong stateful packet and application layer inspection features to VPN connections that it applies to any other connection made to or through the ISA firewall. This sets the ISA firewall’s VPN remote access server component apart from the typical stateful packet inspection-only firewall, where VPN users have the same level of access to the corporate network as a host directly connected to the network.

While many of us made gallant attempts at coming up with comprehensive hardening plans that wouldn’t break core ISA Server 2000 firewall functionality, it always seemed like we were feeling our way through the dark.
