o Modify ipfw(8) to be able set any prefix6 not just Well-Known, and also show configured prefix6; o relocate some definitions and macros into proper place; o convert nat64_debug and nat64_allow_private variables to be VNET-compatible; o add struct nat64_config that keeps generic configuration needed to NAT64 code; o add nat64_check_prefix6() function to check validness of specified by user IPv6 prefix according to RFC6052; o use nat64_check_private_ip4() and nat64_embed_ip4() functions instead of nat64_get_ip4() and nat64_set_ip4() macros. This allows to use any configured IPv6 prefixes that are allowed by RFC6052; o introduce NAT64_WKPFX flag, that is set when IPv6 prefix is Well-Known IPv6 prefix. It is used to reduce overhead to check this; o modify nat64lsn_cfg and nat64stl_cfg structures to use nat64_config structure. And respectivelly modify the rest of code; o remove now unused ro argument from nat64_output() function; o remove __FreeBSD_version ifdef, NAT64 was not merged to older versions; o add commented -DIPFIREWALL_NAT64_DIRECT_OUTPUT flag to module's Makefile as example.

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
