DMZ
If you have a client PC
that cannot run an Internet
application properly from
behind the firewall, you
can open the client up
to unrestricted two-way
Internet access. Enter
the IP address of a DMZ
(Demilitarized Zone) host
on this screen. Adding
a client to the DMZ
may expose your local
network to a variety of
security risks, so it is only
recommended that this is used option as a last resort.
It is also recommended that you disable and software firewall installed
on your PC, this will continue to block ports even if the PC is entered
into the DMZ.
ADSL
ADSL Parameters
We recommend leaving
the Operation Mode at
the default Automatic
setting, to automatically
negotiate with remote
DSLAM (Digital Subscriber
Line Access Multiplexer).
A DSLAM is owned and
managed by your ISP,
if the Modem-Router
is having problems
connecting to the Internet,
it may be necessary to
force the Operation Mode to your ISP’s preferred connection.
