Enabling virtual domains
To make your system present multiple distinct environments
to the outside world, you must enable virtual domains.
On the Internet Services page, select Add or
Enable Virtual Domains. Once you enable virtual domains,
the Internet services on your system are reconfigured
to bind to specific IP addresses. Because of the
difficulties involved in reversing this step, the Internet Manager
will prompt you to verify that this is what you want to do.
Once you make your system's Internet services bind to specific
IP adresses, you cannot reverse this step using
the Internet Manager.
When you enable virtual domains, you must choose which network interface to bind the existing Internet services configuration to. You must choose one of your network cards, a PPP connection, or the localhost interface. localhost always has an IP address of 127.0.0.1 and can only be accessed from the system itself; it is never routed across any network interfaces.
The behavior of the Internet Services page changes after virtual domains are enabled. In addition to the row of buttons used to configure individual services, the Internet Manager presents a list of interfaces to configure, as well as a SYSTEM-WIDE option. localhost (127.0.0.1), your physical network interface(s) and PPP connection(s) are identified as ``physical'' interfaces, while any virtual domains you create (additional IP addresses you add to your system) are identified as ``virtual'' interfaces.
