Not that I can recall, which is why it was a horrible design. IIRC it was just the remote IPMI port, but there may have been a few others. I misremembered [1] the system type, it was the PowerEdge 1855, not the newer 1955. So we did fix that particular bit of pain in newer generations. In that case, it was the IPMI port 623/tcp that was snarfing packets.
