Changes to network settings require rebooting to take effect.
Changes to the Dial Plan do not and will take effect as soon
as they are stored.
Caution
: If you do not store the dial plan, it will be lost
when you reboot.
Note
:
After changing the default IP address, you will be
required to use the new IP Address (hostname), in this
example tvp2.dyndns.org, to gain access to the TVP-221H
via web browser user interface or Telnet.

(NAT) router with built-in DDNS client
Case 5:
Gateway Prefix-Simplified Gateway Phone to Gateway Phone
A major consideration in NAT to NAT VoIP communication is that the DMZ function
and DDNS Client of the NAT routers have to function correctly.
If they do not, it will
result in one-way communication. The following Case example explains how the

TVP-221H can be configured with a Router.
In this example, Trendwares TEW-
431BRP is used.
Internet Access
In addition to fixed IP, the TEW-431BRP can be configured to use PPPoE or DHCP
clients. With PPPoE and DHCP, you will have a Dynamic IP but combined with
Dynamic DNS, the TEW-431BRP will automatically notify DynDNS of your
changing IP Address and DynDNS will in turn, map it to your registered Domain
Name. Assuming the above has been done, we can configure the TVP-221H
Note
: The following installation method takes into consideration that both the TEW-
431BRP and the TVP-221H have the same default IP address: 192.168.0.1. Please
note that the TEW-431BRP DHCP Server start IP Address and finish IP Address
fields set the values used by the DHCP server when allocating IP Addresses to DHCP
clients. Please set the DHCP Server values to avoid conflict with the Fixed IP
addresses assigned to the TVP-221H A (192.168.0.20) and TVP-221H B
(192.168.0.55)
The first time you connect to the TVP-221H for web configuration, you will need to
connect to it under the same LAN segment. To configure the TVP-221H, insert one
end of an Ethernet cable into the RJ45 LAN port of the TVP-221H and the other end
directly to your configuring PC.
Once Internet Access has been configured (See below), you can disconnect the cable
from the PC and reconnect it to one of the LAN ports of the TEW-431BRP. Connect
your PC to one of the remaining 3 Hub ports. By default, the TEW-431BRP’s DHCP
server is enabled. Make sure your computer is DHCP client enabled or has a Fixed IP
not used by any other devices on the LAN. If using a Fixed IP, make sure it is also in
the same LAN segment.. See Chapter 4 for more information. The TEW-431BRP and
the TVP-221H both support auto-MDIX so a Standard Cat 5 cable will be sufficient.
Network Configuration
In this case application, the Trendware TEW-431BRP can be set up to use Virtual
Servers or DMZ, and DDNS Client Support
1.
The TEW-431BRP supports Virtual Servers and DMZ allowing you to connect a
device / server you wish to make available to the public. Using a standard RJ45
cable, connect your TVP-221H LAN port to a TEW-431BRP LAN port.
Please note the following regarding DMZ configuration.
Devices connected to a LAN port are in the same LAN segment as PCs
connected to the other LAN ports. They must use the same IP address range.

DDNS Status should appear. You can also verify by checking the Status page.
Note:
When setting up the DDNS Client,
it is advised that you register a
hostname with only dyndns.org domain.
Note:
DDNS feature implementation may be different for different routers from
different vendors. Please refer to respective vendor’s user’s manual for
DDNS feature explanation and configuration
Note:
Please note that DDNS client in TVP-221H is not suggested in NAT
environments.
