Well, actually they will also be not reacheable, since I am using switch with configured VLAN, so subnets can not physically reach each others. I have done little research and I have noticed : /etc/sysconfig/network-scripts/ifup-routes which seems to use route-$IFNAME and rule-$IFNAME files, passing lines to ip command. Maybe I can try a little game in this area. Thank you and Best Regards, David Hlacik
