TVP-221H User’s Guide

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.

2.Select Internet on the main menu, then Dynamic DNS, to see a screen like the following
