Configuring Servers
Note: If you do not intend to host any public Internet servers in your network (such
as a Web Server, Mail Server, or an exposed host), you can skip this section.
The ZoneAlarm router enables you to configure the following types of public Internet
servers:
• Servers for specific services
You can allow all incoming connections of a specific service and forward them to a
particular host in your network. For example, you can set up your own Web server,
Mail server, or FTP server.
Note: Configuring servers is equivalent to creating simple Allow and Forward rules
for common services, where the destination is This Gateway. For information on
creating more complex rules, see Using Rules on page 172.
• Exposed host
If you need to allow unlimited incoming and outgoing connections between the
Internet and a particular host, you can define an exposed host. An exposed host is not
protected by the firewall, and it receives all traffic that was not forwarded to another
computer by use of Allow and Forward rules.
Warning: Defining an exposed host is not recommended unless you are fully aware of
the security risks. For example, an exposed host may be vulnerable to hacker
attacks.
