Hi, First of all, thanks for your information. Currently the ISA is being in use for WEB Proxy (Cache), but going forward, the ISA will be used for web publishing and such. So I have installed ISA in "intergrated mode", for that specific. That is why I'm thinking I need external facing NIC on our ISA servers.

You must have ISA in firewall or integrated mode to have an external facing NIC. In addition, you must also have a way for an ISA in cache-only mode to retrieve content on behalf of your clients, be it directly from the source or via an upstream server or server chain. -Shawn ----- Shawn R.
