Help❓ Portforwarding.

Ok so basicly, I am portforwarding my server (Well trying). So I have the ports open, but I don't know what IP to put in the client/server configs. If I put both my public ip, I can't connect. If I put my ipv4 in client, and my public IP in server configs I can connect but no one else. Help please? Thanks! P.s. this is fsod source.

Are others able to connect when both are set to your public IP? If they can, I think you need your own client which connects with your IPv4 address and anyone else who is not on your LAN will need a different client with your public IP. If not, there may be a port forwarding issue or some other server config issue.
