I cannot say for certain that this is your problem, but I recall a bug
in the distributed 4.2 code.  In netinet/ip_output.c, inside ip_output(),
if you have a bit of code that reads

	if (ro->ro_rt == 0 || (ifp = ro->ro_rt->rt_ifp) == 0) {
		error = ENETUNREACH;
		goto bad;
	}
	ro->ro_rt->rt_use++;
	if (ro->ro_rt->rt_flags & RTF_GATEWAY)
		dst = &ro->ro_rt->rt_gateway;

change the last two lines to

	if (ro->ro_rt->rt_flags & (RTF_GATEWAY|RTF_HOST))
		dst = &ro->ro_rt->rt_gateway;
