When you install ISA Server on a computer with a single network adapter, ISA Server is only aware of two networks: the Local Host network that represents the ISA Server computer itself, and the Internal network, which includes all unicast Internet Protocol (IP) addresses that are not part of the Local Host network. In this configuration, when an internal client browses the Internet, ISA Server sees the source and destination addresses of the Web request as belonging to the Internal network.
