Minecraft Server hostname can also access router settings

[skortpillet]

I run a minecraft server from home from an internet service that routes one public IP address per household, meaning that the public IP my Minecraft server runs on is also the public IP my dads computer runs on. Just today i was renewing the No-IP hostname and decided to see what happens when I put in the hostname in the chrome search bar and then to my suprise my router login comes up. Does anyone know of a way to block people from accessing my router login when using the hostname?

Have you tried accessing this from outside your network? If you're testing from inside your local network, even if you use the public IP, you'll get to the router's login page but if you try from a phone on 4G for example, you'll likely find it doesn't connect.

 

EDIT: I have a VPN setup using No-IP DDNS. If I go to the public DNS record via LAN I get to my gateway's login page, if I go from outside the network, the connection is refused as the firewall blocks WAN on port 80 and 443 by default. You'd need to explicitly allow access in the firewall to get to it from outside your network.

Like @Oshino Shinoburecommended, try from outside your network. If that still works, block ports HTTP and HTTPS requests to your router from anything outside your subnet.
