MMC is using RPC (aka DCE) protocol. You will need to open port 135 (UDP and
TCP), this will allow to negotiate "real" connection. Unfortunatelly, this
usually means some random TCP port above 1024. I do not think that there is
any way to force negotiating some fixed port for this particular tools, but
maybe someone knows some hack ?
