166 Chapter 10 Managing Server Information
If you turn on rewall security and your server gets its Internet connection through
a network router, you should congure your router to send all incoming requests for
services to your server. For instructions, open Server Preferences Help and search for
“making your server the router default host.”
To allow all incoming requests for services with rewall security:
In the Security pane, click the On/O switch to turn o rewall security. m
While rewall security is o, your server’s rewall allows incoming connections to all
services. However, if your server gets its Internet connection through a cable router,
DSL router, or other router, you also need to congure it to send incoming service
requests to your server. For information about conguring your router, see “Protecting
Your Network with a Router” on page 36.
If you’re using AirPort management (not rewall security), turning it o blocks
incoming connections to all services.
About Firewall Security
The rewall that you can control in the Security pane of Server Preferences is the
Mac OS X Server rewall. Called an IP rewall, it accepts or denies incoming and
outgoing trac based on attributes of the trac, such as its destination port or
originating IP address. For information about the IP rewall, open Server Admin and
then use the Help menu to search for “rewall service overview.”
Your server also has the Mac OS X rewall, which works dierently. It’s known as an
application rewall because it accepts or denies an incoming connection based on
the particular application, service, or other software module that’s trying to accept
the connection. This rewall doesn’t control outgoing network trac. You manage the
application rewall with System Preferences, not Server Preferences.
