F-3
A NonStop system connected as a host in an Internet likewise can act as a gateway
between two subnets, as shown in Figure F-4
. A single NonStop TCP/IP process runs
in the NonStop system, which appears as a single host. In this example, the subnets
are on different LANs.
In Figure F-5, the NonStop system appears as two separate logical hosts, that have
different Internet addresses, connected to a single subnet. Each logical host has its
own NonStop TCP/IP process.
