Not able to connect to my server

Ok so I set up a Ts3 free server on my old pc, first i sent my friends the ip but they couldnt connect. Then i forwarded the ports on my router, still didnt work. Next i made rules for the windows firewall to let connections in and out, that also didnt work. I need help I dont know what to do.

PS: I can connect with my new PC which is in the same network, but i also have to type in the ip from the server and not localhost.
