OK based on the drawing that you have done above - you keep interchanging terms - but i assume what you have labelled as Conduit is also gateway (i.e. Gateway for Lora network devices ?) in your terminology ?
In the diagram your router would be responsible for handing out IP addresses - it will hand them out to hardware devices - Node-Red sits way above this level and has nothing to do with asking for an receiving IP addresses. If you have no control over the Conduit/base station to srt a static IP address (seems strange) - then inside the Router you have to setup the DHCP server to hand out a static address to the MAC address of the Base station each time it starts up.
