Hi, sorry for going to Italian fórum. It was just because with LucaMs understanding should be easier. As a matter of fact, with him, we didn't resolve my problema, though we we were able to fix that the problem is in my router. So, before abandoning the issue, I will follow your indications. I will point out some facts. First of all I let you know that my router has a search for updates, just when it starts, and, regularly, says that nothing new update is available. This update operation could be riskful, because I am all but an expert on this topic. I would prefer not to make any udpate, in these conditions. About the other facts, I observed that, even without restarting the router, the Ip changes. This happened today, for example. But I was carefully checking this fact and I can exclude any change of router public Ip, during my tests. There is a notable thing, emerged during my tests with LucaMs: when I use the "http--ping.eu-port-chk-", on the top of the window appears "my Ip", but this is nothing else that same address reported by WhatIsMyIp, namely the Ip of my Internet provider. This is not my router's Ip. With LucaMs, we reverted our positions and he opened the port and run the server, allowing me to connect. It worked. He showed his window of the http--ping and it reports on the top the same address of his router. I attach the two screens, so you can understand what I mean: for him the top Ip is the same that we must input in the ping while in mine not. Thanks for your attention. Unluckily I am not so expert of these topics, so further instructions can be useless, because I cannot apply them with safety. One thing should be interesting for me: be sure that with you things work, like I did with LucaMs. So, if you can see what happens with your router, and whether the ping reports same address on the top, it can be interesting. As a matter of fact this the only evident difference with LucaMs. Thanks again.
