John at al, The notion of VNC "binding" to a particular _interface_ is bogus. When accepting incoming connections, services "bind" to a particular host _IP address_. Like most other services, VNC binds to INADDR_NONE, which means it accepts connections via all the host's addresses. If your TCP/IP stack is working correctly then this will allow the server to accept connections on any valid IP address for the host, regardless of when they were added to it. The _only_ situation in which VNC Server binds to a specific address is when accepting connections only from localhost.
