Single IP to multiple VM, non standard port

[overopn]

Hi,

I'm new to OPNSense. I want to have one public IP, on listening port 554 which is served to multiple internal NAT VM. With port 80, we can use HAProxy, that is easy but my VM are serving RTSP video to port 554 so there is a TCP handshake followed by outbound UDP to port 554.

Something like this , is that doable with OPNSense.
