DMZ

[ITZPEDROHDI]

is  DMZ same as port forwarding ? and is it recommended 

[DanologyUK]

Putting a device's IP into the DMZ is the same as port forwarding ALL ports for that device. It essentially lets through all traffic but opens you to some risk as all ports are open, should a would-be hacker wish to try and connect. 

I would recommend putting consoles into the DMZ but not a PC for example.

Exactly as above!
