> Does anybody know if it's possible to use Plan 9 as an IPv4 router?
plan 9 does a fine job of routing ip4 packets. i used plan 9
to do that for a 4 months recently during a network renumbering.
if you do this, make sure you've made this revert to ip.c. the
sources version has both lines, which is harmless but redundant.
