Does anyone know if this USB modem works in bridge mode, i.e. exposed the public IP adress to your computer/router? The reason I ask I have tried two different USB 4G modems from Chineese vendors and the both do NAT, i.e. show an local IP adress if you check with ipconfig. This prevents me from setting up a server on the local network. I can't reach the server from internet. I hope this modem does not manipulate the IP adress!
