allows the MTA to advertise itself as an Internet Gateway
Device to PC’s and other devices on the network. For security
reasons it is disabled by default. There may be situations in
which you wish to allow UPnP-capable devices or computers
to gather information about their upstream Internet connection
from the MTA. Do not change this setting unless you are an
expert.
UPnP CP
Enables UPnP CP(Control Point) Function.When the MTA is
connected to a broadband router supporting UPnP IGD, you
should enable this UPnP CP function which may enhance
VoIP service. With it the MTA can configure itself according
to the information it receives from the router or other device
that is further upstream from the MTA. In order to determine
whether your broadband modem supports UPnP PGP, you
must consult the modem manual; however, your broadband
modem manual may not even provide this information. This is
a desirable feature, if your modem supports it.
STUN Configuration: Advanced proxy server settings. Do not change the
defaults unless instructed. Use the “NAT/Conf” link on the main page.
STUN
If a STUN server is available, the MTA can learn additional
information about the path between it and the Internet. If you
do not know whether a STUN server is available, leave this
setting at its default. To enable this feature, click on Enable,
and click the Submit button. To disable this feature, click on
Disable. This feature may possibly be required by your VOIP
Service Provider; see their configuration guides for details.
STUN Server IP
Enter the IP address you wish to connect to the STUN server.
This will be provided by your VOIP Service Provider, if they
use this optional feature.
STUN Server Port
Enter the STUN server Port. This will be provided by your
VOIP Service Provider if they use this optional feature.
Remote Management
: allows you (and others) to access the browser
management screens from a remote location. Do not change these settings
unless you have a very clear understanding of the security issues. Use the
“NAT/Conf” link on the main page.
Remote HTTP
To enable this feature, click on Enable, and click Submit
button. Remote Management must be activated before you
can manage the MTA from a remote location. If you wish to
use this feature on the browser, enter http://Public IP
address:80. To disable this feature, click on Disable.
HTTP Port
To access web browser, the standard HTTP service port 80 is
used. But, to increase web security, this service port can be
changed. The range is between 1024 ~ 65534. Note that if
altered, this port number may not be used by other services
on your network behind the MTA’s NAT.
DMZ Host Configuration
: allows you to directly expose one computer (in
the 192.168.200.0 subnet) to the internet in a DMZ arrangement. Do not
change these settings unless you have a clear understanding of the security
issues. Use the “NAT/Conf” link on the main page. Select Enable or
Disable, then enter the last part of the IP address for the host you wish to
expose.
