CARP(4) - Device Drivers Manual # CARP(4) - Device Drivers Manual
NAME # carp - Common Address Redundancy Protocol
SYNOPSIS # pseudo-device carp
DESCRIPTION # The carp interface is a pseudo-device which implements and controls the CARP protocol. carp allows multiple hosts on the same local network to share a set of IP addresses. Its primary purpose is to ensure that these addresses are always available, but in some configurations carp can also provide load balancing functionality.

NAME # pf.conf - packet filter configuration file
DESCRIPTION # The pf(4) packet filter modifies, drops, or passes packets according to rules or definitions specified in pf.conf.
This is an overview of the sections in this manual page:
PACKET FILTERING including network address translation (NAT).
OPTIONS globally tune the behaviour of the packet filtering engine.
QUEUEING provides rule-based bandwidth and traffic control.

NAME # pf - packet filter
SYNOPSIS # pseudo-device pf
DESCRIPTION # Packet filtering takes place in the kernel. A pseudo-device, /dev/pf, allows userland processes to control the behavior of the packet filter through an ioctl(2) interface. There are commands to enable and disable the filter, load rulesets, add and remove individual rules or state table entries, and retrieve statistics.

Pfsync PFSYNC(4) - Device Drivers Manual # PFSYNC(4) - Device Drivers Manual
NAME # pfsync - packet filter state table synchronisation interface
SYNOPSIS # pseudo-device pfsync
DESCRIPTION # The pfsync interface is a pseudo-device which exposes certain changes to the state table used by pf(4). State changes can be viewed by invoking tcpdump(8) on the pfsync interface. If configured with a physical synchronisation interface, pfsync will also send state changes out on that interface, and insert state changes received on that interface from other systems into the state table.

NAME # sasyncd - IPsec SA synchronization daemon for failover gateways
SYNOPSIS # sasyncd [-dnv] [-c config-file]
DESCRIPTION # The sasyncd daemon synchronizes IPsec SA and SPD information between a number of failover IPsec gateways. The most typical scenario is to run sasyncd on hosts also running isakmpd(8) or iked(8) and sharing a common IP address using carp(4).
