FAST_IPSEC(4)	       FreeBSD Kernel Interfaces Manual		 FAST_IPSEC(4)

NAME
     Fast IPsec	-- hardware-accelerated	IP Security Protocols

SYNOPSIS
     options FAST_IPSEC
     device crypto

     net.inet.esp.enable
     net.inet.ah.enable
     net.inet.ipcomp.enable

DESCRIPTION
     IPsec is a	set of protocols, ESP (for Encapsulating Security Payload) AH
     (for Authentication Header), and IPComp (for IP Payload Compression Pro-
     tocol) that provide security services for IP datagrams.  Fast IPsec is an
     experimental implementation of these protocols that uses the crypto(4)
     subsystem to carry	out cryptographic operations.  This means, in particu-
     lar, that cryptographic hardware devices are employed whenever possible
     to	optimize the performance of these protocols.

     In	general, the Fast IPsec	implementation is intended to be compatible
     with the KAME IPsec implementation.  This documentation concentrates on
     differences from that software.  The user should refer to ipsec(4)	for
     basic information on setting up and using these protocols.

     System configuration requires the crypto(4) subsystem.  When the Fast
     IPsec protocols are configured for	use, all protocols are included	in the
     system.  To selectively enable/disable protocols, use sysctl(8).

DIAGNOSTICS
     To	be added.

BUGS
     There is presently	no support for IPv6.

     The IPcomp	protocol support does not work.

     Certain legacy authentication algorithms are not supported	because	of
     issues with the crypto(4) subsystem.

     This documentation	is incomplete.

SEE ALSO
     crypto(4),	ipsec(4), setkey(8), sysctl(8)

HISTORY
     The protocols draw	heavily	on the OpenBSD implementation of the IPsec
     protocols.	 The policy management code is derived from the	KAME implemen-
     tation found in their IPsec protocols.  The Fast IPsec protocols first
     appeared in FreeBSD 5.0.
