How to block host IP from accessing virtual machine website

I am running a virtual Ubuntu machine and my host machine’s private IP is 10.12.63.16. The virtual machine is running a website on http://10.12.63.130/. The virtual machine is a bridged connection to my host.

I am trying to block my host IP from accessing that website. I am trying to sudo ufw reject from 10.12.63.16 to any port 80 but I can still access it on my host machine.

Any ideas?
