Port forwarding from Pc to server

Hello, I have an issue with ‘port Forwarding’
My setup:
Internet -> Modem (wifi) -> Pc -> server
What I is if someone requests to open port ‘1111’ like http://80.60.40.50:1111 that my pc redirects the client to my server, I don’t know if that’s possible.
Router is all port forwarded so it forwards requests to my pc

You have your server connected to your PC by means of a crossover cable or something? Why not just get a router for 15 bucks and plug both server and pc into it then forward the ports? Describe your setup a bit more.
