GPS Forwarding - No data being sent to TCP port.

I have a Pepwave MAX Transit Duo but I can’t seem to get any GPS data to be forwarded to my server that is listening.

I have a ubuntu server running a simple node application that is listening on port 3200 for data. I have configured the pepwave GPS forwarding to the IP address of this server with the correct port and using TCP.

I can connect to the server from my personal laptop (which is using the Pepwave router’s AP), and I can send data via putty on port 3200.

I have specific outbound rules setup, with one for the routers lan but I checked the router can see the internet because I can run pings and traceroutes outbound from the pepwave device.

I can’t figure out why no data is being sent to my server, I can’t see anything in the event logs either.
