Thanks, I have understood the problem. In Italy the ISP don't give the IP public for 4G LTE connection (the ip adress is an NAT address). For this reason my request is not realizable.

Model : Hardware Version : Firmware Version : ISP : I have a router TL-MR6400 that I use only as router 4G LTE whit a SIM card. After configuration my pc access to Internet. But I need to permit...
