Yep. iptables -j ROUTE -h | grep -i ROUTE gives no output at all. So CentOS and/or RHEL must need rebuilding like you said. I was actually trying to ROUTE to an IP alias to get around an ipsec problem introduced by a Red Hat patch. If I have to rebuild something either way, I'll go straight to the source of the trouble and recompile openswan without the problem patch.
