The location etc. is nor relevant.

OK.

1. Why _desktop_? If it is a firewall you do not want or need a desktop.

2. Actually, if it is a firewall you are probably better off with a
firewall distro.

I used to use Smoothwall: https://www.smoothwall.org/

It was forked to create IPCop. That is long dead but it has been
replaced with IPFire:

Another well-regarded alternative is OPNsense:

Ubuntu is not the tool for this job. Ubuntu *Desktop* _definitely_ is not.

2. Directly on the computer? Then why ask this:

No, you can't. You can only connect to VMs. This is not a VM. You said
it was on a computer you bought.
