I don't think so, as I've never been able to get wireless to work (aside from your hack of routing through the wired interface)... Isn't the binding done in VBox itself and not in PROTOCOL.INI? PROTOCOL.INI says: [TAP_nif] DriverName = TAP$ HandleArps = 1 And if no VM is running, then it shouldn't matter, should it? That configuration is stored in the xml for the VM. I ran all of my tests with nothing else (in terms of networking apps) running. -- Lewis ------------------------------------------------------------- Lewis G Rosenthal, CNA, CLP, CLE Rosenthal & Rosenthal, LLC www.2rosenthals.com Need a managed Wi-Fi hotspot? www.hautspot.com Secure, stable, operating system www.ecomstation.com -------------------------------------------------------------
