What ports and protocols are necessary to be permitted on a firewall for a node to configure multiple UPS by using UPS bulk configuration utility initutil.exe? It appears to be FTP based on ports 20/21 but I had our network admins open those ports up and the utility is still not progressing. On an ad-hoc network the utility works fine.
I didn't notice any reference to any ports/protocols on the system requirements.
