Firewall Client for ISA Server can be optionally installed on client computers protected by Microsoft ISA Server. Firewall Client for ISA Server provides enhanced security, application support, and access control for client computers. Firewall Client for ISA Server provides authentication for Winsock applications that use TCP and UDP, supports complex secondary protocols, and supplies user and application information to the ISA Server logs.
Firewall Client sends user information transparently with each request, enabling you to create a firewall policy on the ISA Server computer with rules that use the authentication credentials presented by the client. ISA Server allows you to configure automatic discovery for Firewall client computers, using a WPAD entry in DNS or DHCP to obtain correct Web proxy settings for clients, depending on their location.
