Does DMZ affect port forwarding?
A DMZ (demilitarized zone) on a home router refers to a DMZ Host. A home router DMZ host is a host on the internal network that has all UDP and TCP ports open and exposed, except those ports otherwise forwarded. They are often used a simple method to forward all ports to another firewall/NAT device.
Why is DMZ not working?
Check from an external host: maybe there is no problem to solve, just the DMZ feature not working from inside. Check that the exposed services are reachable on the INTERNAL IP. Check the presence of firewall features on the router. Check that the target of port forwarding has the default gateway correctly set.
Can you port forward and DMZ at the same time?
Yes, you can perform DMZ to a single LAN IP within your network and do port forwarding simultaneously.
Should I turn DMZ on?
A true DMZ is basically a section of your network that is exposed to the internet but do not connect to the rest of your internal network. However, most of the home routers offer DMZ setting or DMZ host settings. In fact, you generally should not use the home router’s DMZ function at all if you can avoid it.
