Means Firewall Packet Filter.
The most popular and best Linux firewall is Iptables. IPCop, Shorewall, Uncomplicate Firewall, Checkpoint and OpenBSD PF are also on the most popular list.
Someone can make PF changes using their firewall. However, one should take extra caution when changing their PF and should know what they're doing before even attempting to do it.

FreeBSD 7.2 is a legacy RELEASE from the STABLE 7-series tree.
Both Solaris and FreeBSD share a common idea base. The BSD distribution from Berkeley was the starting point for FreeBSD and for SunOS, which is the earlier version of Solaris. As it stands, FreeBSD was developed primarily for the Intel-based chip, whereas Solaris runs primarily on the SPARC chip developed by Sun Microsystems (now part of Oracle). Lastly, Solaris is a proprietary, cost-based version of Unix, whereas FreeBSD is an open-source version.
