He told me that he opened tcp and udp in both ways(inbound and outbound). 8766 wasn't blocked as he told, coz he put it in exception list. He will try to restart PC.
He does not has a router, only direct cable, and the provider opened all ports. And he bought a white IP and settings are made under the opportunity to open the server. Also he is using win 10 and maybe its something blocking from the system.
When he is truing to run the dedicated server - No UPnP-enabled Internet gateway found, you must configure port forwarding on your gateway manually in order to make your server accessible from the Internet.
(it means he has to make UpnP?)
Or it's possible to open a proper server only using router?
So he tried to use the router, opened these UPnP, but its still written tthe same (No UPnP-enabled Internet gateway found, you must configure port forwarding on your gateway manually in order to make your server accessible from the Internet)
