Cpp server The client cannot connect to the server.

I want other people in different local networks to connect to my server. That is, I first have to go to the router, create a virtual server with the IP address of my computer in DHCP (192.168.1.101), with port 1111, with TCP and UDP protocols. Then, on the server side (Server.cpp) I have to set the parameter 127.0.0.1 and port 1111 in inet_addr (), and on the client side I have to specify the white IP address in the inet_addr () (that can be found in https: // 2ip. ru / ) and port 1111. As a result, I start the server and it starts normally, but I launch the client and after 10 seconds it says that it cannot connect to the server. I can not understand what I'm doing wrong ...

Server.cpp
