  Summer of Code 2005: improve libalias - part 2 of 2
  With the second (and last) part of my previous Summer of Code work, we get:
  -ipfw's in kernel nat
  -redirect_* and LSNAT support
  General information about nat syntax and some examples are available
  in the ipfw (8) man page. The redirect and LSNAT syntax are identical
  to natd, so please refer to natd (8) man page.
  To enable in kernel nat in rc.conf, two options were added:
  o firewall_nat_enable: equivalent to natd_enable
  o firewall_nat_interface: equivalent to natd_interface
  Remember to set net.inet.ip.fw.one_pass to 0, if you want the packet
  to continue being checked by the firewall ruleset after being
  NOTA BENE: due to some problems with libalias architecture, in kernel
  nat won't work with TSO enabled nic, thus you have to disable TSO via
  ifconfig (ifconfig foo0 -tso).
