This is a bit thin on details, so just guessing from my side. RPC traditionally uses a moving port, assigned by the port mapper. You can configure it to behave as you want it to (RPC and naive, port based firewall rules have always been a bit at odds with each other.). Perhaps you are seeing that? What on earth is "unhide-tcp"?
