RUT240 reverse VPN access to MQTT?

Hi!

Please excuse any ignorance!
I have a RUT240 in my RV, along with some sensors (humidity etc.). I have enabled the MQTT broker, and verified that it runs properly and receives data.
To use the data and avoid cloud services I have set up a VPN tunnel to my home network. I can access devices on my home network over the tunnel, and I can access the RUT (web interface) from my home network.
However, despite several hours of work, I cannot seem to access the MQTT broker from the home network. I get a connection refused error (NW 61).
I have checked the Firewall on the RUT, and it has rules from wan->mqtt, which I have attempted to switch to openvpn (which I think is incorrect, as I’m guessing that is the vpn service, not the client). I have also attempted to use a manuall config file for MQTT (Mosquitto) to listen to 0.0.0.0 (all interfaces).

So, my question is basically: Is what I am attempting possible, or will the RUT in VPN-client/tunnel mode refuse mqtt connections “in reverse” (ie. from the remote LAN it is tunneled into)?

Thanks in advance!

Hello Dan,

Yes, in this case, from your described setup it should be possible to reach the MQTT broker from WAN (remote networks). To let the RUT240 MQTT broker accept connections from your home network or WAN, please make sure the ‘Enable Remote Access’ slider in the router’s WebUI MQTT → Broker page is on. More information on RUT240 MQTT broker functionality can be found here. Also, what VPN service are you using? Additionally, could you provide screenshots from the MQTT → Broker, Firewall → Traffic Rules sections and a troubleshoot file? Information on how to download it can be found here. Since we do not have direct messages possibility on this forum. I’ve sent you Hubspot instructions. Follow them to attach a downloaded TS file.
