In the CS 1.6 game, servers can be set up using HLDS. However, the server's IP address operates through the IP address of the person who opened it. So when I open a CS 1.6 server, my friends connect through my home's IP address. I want to change it or open it using a different IP address so that they don't have my home's IP address. Sharing my home's IP address doesn't seem rational to me. How can I achieve this?
