Question about port forwarding
Question about port forwarding
This setup isn't a DMZ but an "exposed host" that sends all incoming traffic to the PC associated with the IP address you entered. It seems unnecessary and could pose security risks, though it might be acceptable for your specific case. Ideally you shouldn't use this approach, but if other options fail, it could work. I don’t suggest it. What I’m unsure about is what else to do. In theory, your subnets might be misconfigured, but that’s unlikely. You could try adding a separate rule on your server to allow port 25565 through its firewall, which might be blocked. For example, refer to this guide: Another possible fix is establishing a VPN connection between you and your friend to connect them to your network. I used this method before with Hamachi, though you’d need to create a session each time they joined.
I managed to complete the setup by using TCP/UDP ports 25565 and assigning an IPv4 address to the DMZ. As for your question, I don’t suggest doing that because it can pose security risks if not handled properly. It’s important to evaluate the necessity and safety before proceeding.
