Be aware, if you have connected your EM4720 behind another modem/router that
your External IP address first needs to be forwarded in your modem/router otherwise
your modem/router will still be the one that blocks the ports that you just have opened
through your EM4720.
8.7 DMZ
A demilitarized zone (DMZ) is a security method for separating the internal LAN from
untrusted external networks. So if you enable DMZ this will result that all ports will be
opened from external network, example playing online games or transferring files via
internet.
1. From the left-hand menu, click on “Firewall” – “DMZ”.
