III-5-3. DMZ
A Demilitarized Zone (DMZ) is an isolated area in your local network where
private IP addresses are mapped to specified internet IP addresses, allowing
unrestricted access to the private IP addresses but not to the wider local
network.
You can define a virtual DMZ host here. This is useful for example, if a
network client PC cannot run an application properly from behind an NAT
firewall, since it opens the client up to unrestricted two-way access.
Enable DMZ
Check/uncheck the box to enable/disable the
device’s DMZ Host function.
III-5-4. DDNS
Dynamic DNS (DDNS) is a service which provides a hostname-to-IP service for
dynamic IP users. The changing nature of dynamic IPs means that it can be
difficult to access a service provided by a dynamic IP user; a DDNS service
though can map such dynamic IP addresses to a fixed hostname, for easier
access. The router supports several DDNS service providers, for more details
and to register for a DDNS account please visit the DDNS providers website(s),
examples of which are listed below.
