I have ISA running as a Proxy Caching Server behind a firewall and want to enable FTP Upload (which the firewall rules will allow). I believe I have to switch the mode of operation to "Integrated" which will then give me the full FTP Protocol Definition under the Policy Elements. If I then apply the full FTP Protocol Definition to the User Group configured in Protocol Rules will this then allow FTP Upload to this group ? Or is there someting else I need to do. The box only has one NIC will it require another in Integrated mode ? TIA Ian
