In fact, if each interface had the same IP, then the whole network in that IP range, on the server, would be problematic - and there would be not traffic flowing through. For TCP/IP to work properly, each interface has to have a unique IP address (and depending on the subnet, a different subnet mask / gateway pair as well). Each XEN interface is also a seperate interface, but it uses the bridgetools to work properly - i.e. connect directly to the external network. -- Kind Regards Rudi Ahlers -------------- next part -------------- An HTML attachment was scrubbed...
