USING IPFW2 IN FreeBSD-STABLE
      ipfw2 is standard in FreeBSD CURRENT, whereas FreeBSD STABLE still uses
      ipfw1 unless the kernel is compiled with options IPFW2, and /sbin/ipfw
      and /usr/lib/libalias are recompiled with -DIPFW2 and reinstalled (the
      same effect can be achieved by adding IPFW2=TRUE to /etc/make.conf before
      a buildworld).

# echo "IPFW2=      YES" >> /etc/make.conf
# cd /usr/src/lib/libalias
# make clean && make && make install && make clean
# cd /usr/src/sbin/ipfw
# make clean && make && make install && make clean
