Question about firewall and dmz

Hello mates,

I don't know if I should put my computer in a dmz because it look more secure than my very old and basic router (~2007)

[root@archlinux]: /home/xxxxxx># nmap 192.168.0.0/24
Starting Nmap 7.70 ( https://nmap.org ) at 2020-04-06 03:22 AKDT
Nmap scan report for 192.168.0.254
Host is up (0.0011s latency).
Not shown: 997 filtered ports
PORT     STATE SERVICE
80/tcp   open  http
554/tcp  open  rtsp
9100/tcp open  jetdirect
MAC Address: xx:xx:xx:xx:xx (Freebox SAS)

Nmap scan report for 192.168.0.12        
Host is up (0.000019s latency).
All 1000 scanned ports on 192.168.0.12 are closed

Nmap done: 256 IP addresses (2 hosts up) scanned in 26.64 seconds

What object would be more secure in the DMZ?  Where is it currently?  From what would it be more secure?

No.

The DMZ puts your machine on the wrong side of the firewall and exposes it to direct attack from the public internet.
