Packet Filter bundled in the upcoming Oracle Solaris 11.4
Oracle Solaris 11.4 includes the OpenBSD Packet Filter (PF) firewall for filtering TCP/IP traffic. PF firewall is a replacement to the IP Filter (IPF) in Oracle Solaris 11.4, enabling both bandwidth management and packet prioritization.
To use the PF firewall simply install the
pkg:/network/firewall package and enable the service
Note: Make sure you configure the firewall before enabling the service. The default configuration puts the service to a degraded state. The degraded firewall blocks all inbound sessions except ssh. Outbound sessions are allowed.
PF includes the
pflogd feature, a packet logging daemon that safely saves packets logged by the PF firewall. These packets are available from a capture datalink. The daemon reads packets from this datalink and stores them into a file. For more information, see the pflogd(8) man page.
ftp-proxy, a semi-transparent proxy for FTP, supporting IPv4 NAT. Systems running the PF firewall for NAT can use the ftp-proxy to allow FTP connections to pass through the firewall. For more information, see the ftp-proxy(8) man page.
For more information, see Chapter 3, "Oracle Solaris Firewall" in Securing the Network in Oracle Solaris 11.4 and the pfctl(8), pf.conf(7), and pf.os(7) man pages.
