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 IP60 appliance 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 238.
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.
To allow services to be run on a specific host
1. Click
Security
in the main menu, and click the
Servers
tab.
The
Servers
page appears, displaying a list of services and a host IP address for each allowed service.
