Quick notification regarding Teltonika RUT950 WebUI connectivity

Hello, regarding an issue caused in this thread Issue: Teltonika RUT950 WebUI access through VPN - #3 by AndzejJ

The problem was the NMC/QMI protocol the SIM card uses to communicate. After the firmware update listed there, connecting to the WebUI through the VPN address does not work no matter what. Before the firmware upgrade, it worked fine through those protocols. Changing it to PPP made it work instantly, though we are limited in reliably using NCM/QMI from now on which is why I’m notifying you in hopes of helping you resolve the issue with the newest firmware update.

Kind regards.


The RutOS v7+ does not have an option to choose PPP. It uses QMI. Could you please clarify what firmware version do you have installed on RUT950?

Please, navigate to Network → Interfaces → Mob1s1a1 → Advanced settings and try lowering MTU. The values to try are 1460, 1360, 1260. Let me know how it goes.

Kind Regards,
