So if that's what you want, then you can use the notation in the second IP listed above for all of them. </div><div><br></div><div>Now one thing that will change here is that Spread will no longer use the localhost (127.0.0.1) interface either (unless you add it to the list of interfaces to use in the above configuration). So a connection from a Spread client application to a daemon on the same machine will no longer be able to use the localhost TCP but will have to use the primary interface IP of 10.151.140.X. That may reduce the client-server performance slightly as TCP localhost is often faster then through physical ethernet cards. Also</div><div><br></div><div>I would try this type of configuration and then run netstat again and see if it is binding to the interfaces in the way you want. </div><div><br></div><div>Cheers,</div><div><br></div><div>Jonathan</div><div><br></div><div>
