No, you can't stop phone-home behaviour with a hardware firewall if it behaves like regular traffic (hitting port 80 forex). That requires either something running on the machine itself and monitoring network traffic or a content-based filtering appliance running on or beside the hardware firewall. Firewalls themselves only block classes of traffic or destinations (typically you block by IP and/or port for outgoing and permit by IP and/or port for incoming traffic). An application which is monitoring traffic on a per-app basis may be called a software firewall but that doesn't make it function like the hardware kind. IN this case it's much more capable, it remains far less capable at effectively blocking inbound traffic. -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
