Multi-networking with ISA Server 2004

ISA Server 2004 introduced “multi-networking” support. What this means is that it is possible to deploy an ISA server across multiple physical network segments, as illustrated in Figure 5.1. The goal of this is to filter, control, and monitor the traffic that traverses between the networks. In essence, this allows ISA to then become a true firewall for the traffic between multiple network segments.
