Is DMZ in a router safe with a software firewall?

Hello everyone!

After I’ve found that it was really annoying, I’ve decided on putting my internet in DMZ for allow my gaming network. I know port forwarding is the right method, but I’m having some problems lately.
The DMZ seems to be the easiest solution, but at the cost of security.

So, I would like to know, with Comodo firewall installed (or any software firewall), does enabling DMZ result in security loss? I would like to get some detailed information.

Thank you! :slight_smile:

If you decide to run a DMZ, you are removing a layer of protection that your router provides. (Hardware firewall or NAT) So yes, doing so results in a security loss.

Comodo is a very capable firewall though, and you’d be just as protected running with just Comodo as any of the users without a router.
