What happens if you just remove the ifcfg file for this interface? What does Xen do with it? What if you have an ifcfg file, but setup no IP address on it? Of course you can pass the NIC through to the PVM which I suspect is what you are thinking of doing. > (Now to find another Linux firewall appliance as I was using > pfSense and it doesnt play nice with Xen) There is shorewall which is in the repo. Or maybe smoothwall can run inside a PVM? -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
