What is the Solaris IP Filter firewall?
The Solaris IP Filter firewall is firewall software that allows for stateful packet filtering. It can also be used to deliver network address translation (NAT) capabilities. IP Filter provides protection to a single server or a network of servers and clients. The IP Filter technology included in the Solaris 10 OS is based on the next-generation Version 4.x open source IP Filter. Enhancements made during the Solaris software development process have been placed back into the open source version of IP Filter.
