20.2.3.1 HTTP Server Wizard
The HTTP Server Wizard consists of ve steps. In the last step of the dialog, you are
given the opportunity to enter the expert conguration mode to make even more specic
settings.
Network Device Selection
Here, specify the network interfaces and ports Apache uses to listen for incoming re-
quests. You can select any combination of existing network interfaces and their respec-
tive IP addresses. Ports from all three ranges (well-known ports, registered ports, and
dynamic or private ports) that are not reserved by other services can be used. The default
setting is to listen on all network interfaces (IP addresses) on port 80.
Check Open Port In Firewall to open the ports in the rewall that the Web server listens
on. This is necessary to make the Web server available on the network, which can be
a LAN, WAN, or the public Internet. Keeping the port closed is only useful in test sit-
uations where no external access to the Web server is necessary. If you have multiple
network interfaces, click Firewall Details... to specify on which interface(s) the port(s)
should be opened.
Click Next to continue with the conguration.

single physical machine. The rst declared virtual host in the conguration le is
