Advanced Setup; Port Settings; Port Forwarding - Vonage VDV21-VD User Manual

Advanced Setup

Now we come to the advanced settings of the V-Portal. Most users will never need to adjust any
of the settings in this section. Many of the settings in this section require advanced networking
knowledge. Incorrectly changing these settings may interrupt your Internet or voice service. We
recommend that only users with sufficient networking knowledge change these settings or users
who are instructed to do so by a member of Vonage's Customer Care team.
The Advanced Setup section of the Web UI has eight sub-menus.
T he eight sub-menu entries are
•

Port Settings

•
Ethernet Options
•
Filtering
•
Parental Controls
•
Network Options
•
Firewall Logs
•
Factory Defaults
•
QoS
Port Settings
The Port Settings scr een is where you can setup the following items:
•

Port Forwarding

•
Port Triggering
•
DMZ Host
As stated previously, most users will never need to change these settings. However, if you are

g ames you may need to adjust settings in this section. Not all Internet applications require
c hanges to the port settings. As a general rule of thumb, if your application or device worked fine
when connected d irectly to your modem but does not work when connected behind your V-Portal,
y ou may need to customize port settings.
Although not required, we recommend you assign a static IP address to the PC when
implementing Port Forwarding or a DMZ Host. This will prevent the situation where your po
settings may stop working and need to be reassigned as a result of your PC receiving a new IP
address. For example, if DHCP is enabled on your PC and there is a power failure, when the
power comes back on the PC may have a different IP address. All of your port settings will stop
nctioning. Assigning a static IP address eliminates this possibility.

Let's take a close r look at each of these.
Port Forwarding
P ort Forwarding is a technique where incoming packets destined for a specific port on a machine
a re re-directed or 'forwarded' to a different port and/or machine. Network clients do not know that
port forwarding is being done.
