3.99.17/19 is about half a year old.  At this point, my recommendation is to
try to use a NetBSD-4 branch kernel (one is available from releng.netbsd.org)
which will already have the option.  That will at least tell you if the
kernel will work.

Try things out in single user mode, without deleting anything already on
your system.  (ie: boot single user mode, add nat/filter rules, run a test)

-=erik.


Very basically, get the syssrc.tgz package, and put it in / and untar
