Steam does not support gameplay on machines operating in a network DMZ. You must remove your machine from the DMZ in order to play through Steam.

But I am using DMZ in home router (ADSL router - old, 4G router - new). I haven't problem for connection and DMZ is helping to change NAT in Call of Duty from "Strict" to "Open" (Port forward didn't help) and Call of Duty works perfect.
But I have problem in CS GO: no lag, ping 60-90 ms, but bullets aren't registering (sometimes more than 50%). Could DMZ be the cause of this problem? And what alternative of DMZ?

a lot of home routers do not have a real DMZ
http://en.wikipedia.org/wiki/DMZ_(computing)

Some home routers refer to a DMZ host. A home router DMZ host is a single address (e.g., IP address) on the internal network that has all traffic sent to it which is not otherwise forwarded to other LAN hosts. By definition this is not a true DMZ (demilitarized zone),

Thank you =) Does it mean that home "DMZ" isn't problem for steam?

I do not think so and it is just not a secure thing to be using.

no need to do anything to a router for normal steam use.
