IP Umbrel in DMZ Router

Good morning everyone, I have a doubt, I would like you to explain and help me please, having installed umbrel on my personal computer, local network (http://umbrel.local/login), and how to make my node visible for all I have to put the umbrel.local IP in the DMZ on my router, I would like to know if I am not compromising the security of my computer. Or it would be better to install umbrel on the computer just for this purpose. Thanks in advance.
