VII. Management

There are several ways that you can make the configuration:

 Local Ethernet Port (telnet) – connect the Ethernet port to

your local area network or directly to a PC, “telnet” X5821
from any workstation in the LAN. The default local Ethernet
IP address is “192.168.1.1”. See Chapter 2, Command Line
Interface, for more details.

 Local Ethernet Port (Web browser) – connect the Ethernet

port to your local area network or directly to a PC. Launch
your Web browser and enter default local Ethernet IP
address “192.168.1.1” into the address bar.

 ADSL Port from Remote Site – while the ADSL connection

is in service and it is set to router mode, you may remotely
“telnet” X5821 from a workstation connected to the
equipment.

Note: As operating an ADSL device requires technical know-how and
experience, it is recommended that only qualified technical staff manage
X5821 Therefore, a password authentication is required when you enter
the command line and Web interface. See the Default Values section to
obtain the password.

X5821 User’s Manual Version 1.0

4.1.2 PPPoE CONFIGURATION

PPPoE is also known as RFC 2516. It is a method of

encapsulating PPP packets over Ethernet.

PPPoA is also known as RFC2364 and named as Peer to Peer

Protocol over ATM. As PPPoE, it also includes all the features of PPP.

Although it’s based on ATM protocol, the setting of all the other

parameters is similar with PPPoE. So we only describe PPPoE in

detail here.

Select PPP over Ethernet (PPPoE), press “Next step”.

25

X5821 User’s Manual Version 1.0

26

z PPP Account: Your account from ISP to access Internet.

z Password: Input the password assigned by your ISP.

z PPPoE server name: Server name of network ISP. No need to

set.

z Authentication Mode: Authentication mode of network ISP.

Default is AUTO.

z Connection on demand: When this mode is selected, the

connection that has no traffic within assigned

disconnect timeout (e.g. 1 minute) will be automatically

disconnected. The connection will be activated again when

traffic arrives. This function is advantageous for users who are

charged with online time. It should be noticed that some

programs automatically link to Internet. Computer will send data

to network when infected by virus. Connection will not be

disconnected under these data streams.

z Disconnect timeout: When “Connection on demand” is selected,

this input box indicates that after how

long the connection will be disconnected in the absence of

traffic. If the value is 0, connection will not be disconnected.

Press “Next step” when configuration is finished. The following

operation is same with Figure 3.5. Notice that PPPoE mode does not

IP settings.

27

Notice: DHCP can be enabled for PVC in MER mode or IP over

Ethernet as WAN interface if "Obtain an IP address automatically" is

chosen. Changing the default gateway or the DNS, this will effect the

whole system. Configuring them with static values will disable the

automatic assignment from DHCP or other WAN connection.

X5821 User’s Manual Version 1.0

If you configure static default gateway over this PVC in MER mode,

you must enter the IP address of the remote gateway in the "Use IP

address". The "Use WAN interface" is optional.

4.2 LAN

Click “LAN” below “Advanced Setup” on the left manual. Access

“LAN” configuration page. The local port settings are used to

join port not all ports. This way will prevent the video streams
generate packets storm.

 Enable DHCP Server: This setting to enable/disable DHCP

server.

 Start IP Address: Enter the first IP for the address pool.
 End IP Address: Enter the last IP for the address pool.

4.3 NAT

There are three pages to set NAT related functions include

Virtual Servers, Port Triggering, DMZ Host. The following

sections will describe page by page.

4.3.1 Virtual Servers

Access “Virtual Servers” to enter the page below. This

page is to open related ports for specific applications. This

page allows you to configure the port forwarding feature of

this device. This feature works in conjuction with NAT/PAT

and the firewall.

X5821 User’s Manual Version 1.0

Port fowarding can be used to provide local services for

networks or node on the Internet in order to use special

applications or play games.

Virtual Server allows you to direct incoming traffic from

WAN side (identified by Protocol and External port) to the

Internal server with private IP address on the LAN side.

The Internal port is required only if the external port needs

to be converted to a different port number used by the

server on the LAN side. A maximum 32 entries can be

configured.

30

X5821 User’s Manual Version 1.0

4.3.2 Port Triggering

Some applications require that specific ports in the Router's firewall

be opened for access by the remote parties. Port Trigger dynamically

opens up the 'Open Ports' in the firewall when an application on the

LAN initiates a TCP/UDP connection to a remote party using the

'Triggering Ports'. The Router allows the remote party from the WAN

side to establish new connections back to the application on the LAN

side using the 'Open Ports'. A maximum 32 entries can be

configured.

31

X5821 User’s Manual Version 1.0

32

X5821 User’s Manual Version 1.0

4.3.3 DMZ Host

belong to any of the applications configured in the Virtual Servers

table to the DMZ host computer. Enter the computer's IP address

and click "Apply" to activate the DMZ host. Clear the IP address field

and click "Apply" to deactivate the DMZ host.
