FAST_IPSEC(4) BSD 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 cryptograph 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 subsystem. When the Fast IPsec protocols are configured for use all protocols are included in the sys- tem. 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 be- cause of issues with the crypto subsystem. This documentation is incom- plete. SEE ALSO 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. BSD January 20, 2003 BSD
