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.

minooka; diff -c /n/dump/2010/0930/sys/src/9/ip/ip.c /n/dump/2010/0820/sys/src/9/ip/ip.c
/n/dump/2010/0930/sys/src/9/ip/ip.c:463,469 - /n/dump/2010/0820/sys/src/9/ip/ip.c:463,469
  		}

  		/* don't forward to source's network */
- 		memset(&conv, 0, sizeof conv);
+ 		conv.r = nil;
  		r = v4lookup(f, h->dst, &conv);
  		if(r == nil || r->ifc == ifc){
  			ip->stats[OutDiscards]++;
