IP Firewall Service Overview

What Is IP Firewall Service?

Firewall service is software that protects the network applications running on your Mac OS X Server. Turning on firewall service is similar to erecting a wall to limit access. Firewall service scans incoming IP packets and rejects or accepts these packets based on the set of rules you create. You can restrict access to any IP service running on the server, and you can customize rules for all incoming clients or for a range of client IP addresses.
