FIGURE 11.2 Understanding SecureNAT clients in a complex network configuration.
NOTE
It is very common to have Web Proxy clients also displayed as SecureNAT or Firewall
clients in the ISA Server monitoring tools. This is because, fundamentally, the description
of a Web Proxy client simply refers to the web browser??“based application traffic
that comes from a SecureNAT or Firewall client.
Outlining the VPN Client
Technically speaking, ISA Server recognizes a fourth type of client: Virtual Private Network
(VPN) clients. A VPN client is a client system that remotely establishes an encrypted
tunnel to an ISA server. For more information on VPN clients and for deployment scenarios
involving them, see Chapter 9, ???Enabling Client Remote Access with ISA Server 2006
Virtual Private Networks (VPNs).???
Preparing an ISA Environment for the Firewall Client
By default, ISA Server 2006 does not automatically enable an environment for support and
installation of the Firewall client component.
