If this is the case, how do I go about overridding this. The term "non routable" is a misleading term. There is nothing special about 10.0.0.0/8 172.16.0.0/16, and 192.168.0.0/18, other than that people have agreed not to globally route these blocks. What you need is to add routes on the box that link the two networks together (which should be done automatically if it has interfaces in both networks), enable IP forwarding on the box, and make it the default gateway (or add static routes on your machines) for your machines. ---Mike Mike Tancsa (mdtancsa@sentex.net) Sentex Communications Corp, Waterloo, Ontario, Canada "Given enough time, 100 monkeys on 100 routers could setup a national IP network."
