RMS Connect can only operate on one port at the same time.
If multiple ports are needed, or a non-standard protocol is being used, then VPN quick connect is the best service to suit your needs. It creates a VPN tunnel between the device you'd like to access and the device that you are using. It should be kept in mind, that this service is VPN-based, so it might take a little more time to get running.
Hope this helps!
