C2-010 / C2-010-I ADSL2+ Router User’s Guide

So, if you want to use an IP addressing scheme that is different from the 192.168.1.x/255.255.255.0

scheme, you will need to give the ADSL2+ Router ADSL router a new IP address.

This is done on the

LAN

Settings

page, as shown below.

To access the

LAN Settings

menu, click the

LAN

button in the

Home

directory.

Figure 4-10. Configure LAN IP settings

To change the

LAN IP Address

or

Subnet Mask

, type in the desired values and click the

Apply

button.

The new IP settings must be saved and the ADSL2+ Router must be restarted for the settings to go into

effect. To manually

Save & Restart

the ADSL2+ Router, click on the

Tools

directory tab and then click the

System

menu button. Then click the

Save&Restart

button. The ADSL2+ Router will save the new IP settings

and restart. Your web browser should automatically be redirected to the new IP address.

5. Advanced Configuration

This chapter introduces and describes the management features that have not been presented in the

previous chapter. These include the more advanced features used for network management and security as

well as administrative tools to manage the ADSL2+ Router, view statistics and other information used to

examine performance and for troubleshooting.

Use your mouse to click the directory tabs and menu buttons in order to display the various configuration

and read-only menus discussed below.

The table below summarizes again the directories and menus

available in the management web interface. In this chapter you will find descriptions for the menus located in

the Advanced, Tools and Status directories.

Virtual

server

This page allows you to configure the ADSL2+ Router ADSL router to allow remote users to

assess service such as web or FIP service through a public IP address.

Application

This page allows you to configure r\the ADSL2+ Router ADSL router to allow applications that

require multiple connections such as Internet gaming, video conferencing, Internet telephony,

and others that are unable to work through Network Address Translation (NAT)

Filter

Filters are used to deny or allow access to the Internet for various PCs on your LAN. The

ADSL2+ Router can refuse PCs on your LAN access to the Internet based upon their IP or

MAC address, or it can restrict access to specific web sites.

DMZ

If your computer cannot run Internet applications property with the device, then you can enable

this option to allow the computer accessing the unrestricted Internet. Enter the IP address of

the computer as a DMZ (Demilitarized Zone) host. Adding the computer to the DMZ may

expose it under insecurity risk; thus suggest not use this option unless no other alternatives.

DDNS

This page allows you to configure the ADSL2+ Router to use the DYNAMIC Domain Name

Service (Dynamic DNS), if you have a previously established account.

RIP

This allows you to enable or disable the Routing Information Protocol (RIP) on PVC’s that allow

routing.

5.1 UPnP Configuration

UPnP supports zero-configuration networking and automatic discovery for many types of networked

devices. When enabled, it allows other devices that support UPnP to dynamically join a network, obtain an IP

address, convey its capabilities, and learn about the presence and capabilities of other devices. DHCP and

DNS service can also be used if available on the network. UPnP also allows supported devices to leave a

network automatically without adverse effects to the device or other devices on the network.

UPnP can be supported by diverse networking media including Ethernet, Firewire, phone line and power

line networking.

Figure 5-2. UPnP menu

To enable UPnP for any available connection, click to check the

Enable UPnP

selection box, select the

connection or connections on which you will enable UPnP listed under

Available Connections

and click the

Apply

button.

5.2 Virtual Server Configuration

To view the following window, click on the

Advanced

tab at the top of the window and then click the

Virtual

Server

button to the left. The

Virtual Server

will allow remote users access to various services outside of

their LAN through a public IP address, such as FTP (File Transfer Protocol) or HTTPS (Secure Web). After

configuring the Router for these features, the Router will redirect these external services to an appropriate

server on the user’s LAN.

These external services may be modified by clicking its corresponding edit icon, or they may be deleted by

clicking the corresponding delete icon. Though there are seven fields available to configure the Virtual

Server, in most cases, only the IP address of the Virtual Server will be needed for implementation. To enable

an already existing Virtual Server, click its corresponding edit button, configure the appropriate fields listed

below and set the

Status

fields to

Enabled

by clicking the radio button. To configure other virtual servers for

the Router, configure the following fields and click

Apply

.

circumstances.

Destination

Port

Enter the port number of the device on the WAN side of the network that will be accessing

the Virtual Server currently being configured. Commonly, this port number is identical to the

Private Port number. Existing Virtual Servers listed already have their well-known port

number listed yet this may need to be changed in certain circumstances. You can specify a

range of ports, a single port, save ports, or any port.

Click the

Apply

button to put the new virtual server configuration set or modification into effect. Any

server sets configured in the menu will appear in the Virtual Server List with the new settings. The ADSL2+

Router must save the new settings and reboot before the new virtual server configurations are applied.

To remove any configuration set from the Virtual Server List, click on the trashcan icon for set you want

to delete.

5.3 SNMP Configuration

Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically

for managing and monitoring network devices. SNMP enables network management stations to read and

modify the settings of gateways, routers, switches, and other network devices. Use SNMP to configure

system features for proper operation, monitor performance and detect potential problems in the Switch,

switch group or network.

The default community strings for the Switch used for SNMP v.1 and v.2 management access are:

public - Allows authorized management stations to retrieve MIB objects.

private - Allows authorized management stations to retrieve and modify MIB objects.

Figure 5-4. SNMP menu

Traps are messages that alert network personnel of events that occur on the Switch. The events can be as

serious as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change.

The Switch generates traps and sends them to the trap recipient (or network manager). Typical traps include

trap messages for Authentication Failure, Topology Change and Broadcast\Multicast Storm.
