Andrez, First of all, you may disable ICMP redirects on A, then route to B will never appear on client machines. Second, you may put B on a different subnet than client machines, the routing entry will not appear either. -- Tomas Beinaravicius System Administrator No Magic P.O.Box 2166, LT-3000, Kaunas
