|Summary. This tutorial was made to enable you to understand why a firewall client is used and also to understand it’s limitations and advantages over other ISA clients. Please NOTE: this tutorial is not here to describe how to configure the firewall client in detail.|
*(The Control channel is a means for the ISA firewall client and the firewall service to communicate information. Authentication, LAT information and name resolution queries are examples of what is sent within the control channel link up. Note: no data is sent along this channel. TCP and UDP Port 1745 is used for port negotiation and DNS queries.)
It is important to understand how the firewall client works in order to select the appropriate ISA client for your organization. Firewall clients also allow you to control Winsock applications more closely. Normally users will try to use IRC and other Winsock applications and if they are configured as normal web proxy users it can prove to be a challenge for them. The information I have highlighted above will help you in deciding if the firewall client is the client you are looking for and hopefully will save you time.
