DNS 
On the Advanced tab, configure the appropriate DNS settings to determine what domains are used 
for assessing online statuses. This setting is generally fine to leave on Auto.
In some cases, setting the DNS statically is necessary. For WFRControl installations, it is recom-
mended to have the outdoor slave set to Auto while the indoor master is statically assigned to 
Google’s DNS servers.

DMZ 
On the Advanced tab, set a DMZ IP Address of a server behind the WiFiRanger. DMZ stands for De-
militarized Zone, which in computer security terms means that this server is exposed through the 
router’s firewall so that access is granted to the DMZ server from the internet.
Hosting a DMZ server behind a WiFiRanger does not compromise other devices or computers on the 
LAN. Only the specified server will be exposed to the internet.
