EC200U + RNDIS + Static IP

Hello,

I’m trying to set up internet connection with EC200U and access HTTP server on it from remote side. I’ve done this with UC200T by enabling NAT AT+QCFG="nat",1. But when I tried to run this command on EC200U, it returns +CME ERROR: Operation not allowed.

command:ATI                   response: Quectel

How can I access HTTP Server from remote?

Hi @snanmre
To enable the nat function, run the following command.
