Mobile Internet

Hello All,

I am having an VERY frustrating issue with mobile internet providers. I have AT&T/Firstnet mobile Hotspot and a T-Mobile Mobile HotSpot. My ASL3 Nodes will connect to them BUT the ONLY node I can get them to connect to is 55553 The Parrot Node in Plano Texas. I can not understand why. I did connect one of my nodes to a Verizon HotSpot of a friend and the connection worked and I was able to connect to any active node. If I were to reach out to AT&T or T-Mobile to discuss possible firewall issues what specifically would I refer to? Ports? DNS?

Here is the weird part. If I enter my cloud hub into the node section of my rpt.conf mobile node i.e. 576335 = radio@198.58.124.150/576335,NONE and I enter my node into the Cloud server rpt.conf file and they will connect!

So Does anyone have ANY idea why I can’t connect? Or What Steps I need to take with the cellular carrier?

Any and ALL help is appreciated.

For anyone who comes across this later, this is an issue where the AT&T and T-Mobile hotspots are handling web/HTTP traffic differently from IAX traffic. IAX traffic is how nodes link. In this situation, the HTTP registration process causes the registration servers to see one IP while the IAX traffic is using a different one. In this limited circumstance, use of IAX-based registration is recommended.

That fixed me up. I am now connecting to nodes!!!

For the record I’m on a T-Mobile 5G home internet connection.

Thank you for what little hair I have left, 73.
