I have linked Node-red to the router and that is working fine via port 1883.
IF I wanted to run this as an external MQTT Broker, I presume I need a static IP address SIM card?
Is there away to get around this?
Hello,
Yes, you would need a SIM card with a static public IP address, but there is another option. You can use a DDNS service instead. Here is more information on it: link to the wiki page.
Kind regards,

Thanks for the info, I have used a DDNS before however will this work with EE SIM card as from my limited research I understand the The EE mobile network uses Carrier Grade NAT (CGNAT) resulting in a double NAT.
So from my testing even when I know my current IP address it doesn’t seem to be contactable, well for sure no ports are open whatsoever when checking.
I have the same issue with my NVR HikVision cctv that runs through a EE sim in Teltonikia unit, never been able to get that to work with DDNS…
However I’m no expert and I could be doing something wrong.
Hello,
You’re correct. If you’re using CGNAT, DDNS or any similar service won’t function. You’ll require a SIM card with a static IP address.

Ah okey, that’s a shame as I use around 1TB of data a month there are no static IP for reasonable money that will support that.
On my ProRouter with same network I got it to work with a VPN, but guess Teltonika doesn’t have this option built in.
This seems to be the biggest limitations of SIM card routers.
Hi,
If you’re considering using a VPN for your solution, our routers support that feature. You can configure multiple VPN services with them. Here’s more information: RUTX50 VPN Configuration Guide

Ah okey, when you said there was no other option I took you at that and wouldn’t have looked into the VPN option, so if that will work I can look into that setup.
Cheers.
