Click Add or Edit to display the following page and add a new static

route to the list.

Parameter Description

Index:

Displays the number of the route.

Network Address:

Enter the IP address of the remote computer for

which to set a static route.

Subnet Mask:

Enter the subnet mask of the remote network for which

to set a static route.

Gateway:

Enter the WAN IP address of the gateway to the remote

network.

NAT Mapping Table displays the current NAPT address mappings. The

NAT address mappings are listed 20 lines per page, click the control

buttons to move forwards and backwards. As the NAT mapping is

dynamic, a Refresh button is provided to refresh the NAT Mapping

Table with the most up-to-date values.

The content of the NAT Mapping Table is described as follows:

•

Protocol - protocol of the flow.

•

Local IP - local (LAN) host’s IP address for the flow.

•

Local Port - local (LAN) host’s port number for the flow.

•

Pseudo IP - translated IP address for the flow.

•

Pseudo Port - translated port number for the flow.

•

Peer IP - remote (WAN) host’s IP address for the flow.

•

Peer Port - remote (WAN) host’s port number for the flow.

Route

These pages define routing related parameters, including static routes

and Routing Information Protocol (RIP) parameters.

Version:

Sets the RIP version to use on this interface.

Poison Reverse:

A method for preventing loops that would cause

endless retransmission of data traffic.

Authentication Required:

None, No authentication.

Password:

A password authentication key is included in the packet.

If this does not match what is expected, the packet will be discarded.

This method provides very little security as it is possible to learn the

authentication key by watching RIP packets.

MD5:

An algorithm that is used to verify data integrity through the

creation of a 128-bitmessage digest from data input (which may be a

message of any length) that is claimed to be as unique to that specific

data as a fingerprint is to a specific individual.

Authentication Code:

Password or MD5 Authentication key.

RIP sends routing-update messages at regular intervals and when

the network topology changes. When a router receives a routing

update that includes changes to an entry, it updates its routing table

to reflect the new route. RIP routers maintain only the best route to

a destination. After updating its routing table, the router immediately

begins transmitting routing updates to inform other network routers of

the change.

Routing Table

RIP Parameter

The device supports RIP v1 and v2 to dynamically exchange routing

information with adjacent routers.

Parameter Description

General RIP Parameters

RIP mode:

Globally enables or disables RIP.

Auto summary:

If Auto summary is disabled, then RIP packets will

include sub-network information from all sub-net works connected

to the ADSL Router. If enabled, this sub-network information will be

summarized to one piece of information covering all sub-networks.

Table of current Interface RIP parameter:

Interface:

The WAN interface to be configured.

Operation Mode:

Disable:

RIP disabled on this interface.

Enable:

RIP enabled on this interface.

Silent:

Listens for route broadcasts and updates its route table. It

does not participate in sending route broadcasts.

The VoIP Router’s firewall enables access control of client PCs,

blocks common hacker attacks, including IP Spoofing, Land Attack,

Ping of Death, IP with zero length, Smurf Attack, UDP port loopback,

Snork Attack, TCP null scan, and TCP SYN flooding. The firewall does

not significantly affect system performance and we advise leaving it

enabled to protect your network.

Note:

After you check the radio button in the “Enable or disable

Firewall features” field, you must click the “SAVE SETTINGS” button

to display the list of firewall features.

Access Control

Access Control allows users to define the outgoing traffic permitted

or not-permitted through the WAN interface. In the example above, all

incoming and outgoing emails are blocked. The default is to permit all

outgoing traffic. (See the following page for details.)

The VoIP Router can also limit the access of hosts within the local

area network (LAN). The MAC Filtering Table allows the VoIP Router

to enter up to 32 MAC addresses that are not allowed access to the

WAN port.

Parameter Description

Flags:

Indicates the route status:

C = Direct connection on the same subnet.

S = Static route.

R = RIP (Routing Information Protocol) assigned route.

I = ICMP (Internet Control Message Protocol) Redirect route.

Network Address:

Destination IP address.

Netmask:

The subnetwork associated with the destination.

This is a template that identifies the address bits in the destination

address used for routing to specific subnets. Each bit that

corresponds to a “1” is part of the subnet mask number; each bit that

corresponds to “0” is part of the host number.

Gateway:

The IP address of the router at the next hop to which

frames are forwarded.

Interface:

The local interface through which the next hop of this route

is reached.

Metric:

When a router receives a routing update that contains a new or

changed destination network entry, the router adds 1 to the metric value

indicated in the update and enters the network in the routing table.

The VoIP Router can also limit the access of hosts within the local

area network (LAN). The MAC Filtering Table allows the VoIP Router

to enter up to 32 MAC addresses that are allowed access to the WAN

port. All other devices will be denied access.

URL Blocking

To configure the URL Blocking feature, use the table below to specify

the web sites (www.somesite.com) and/or keywords you want to filter

on your network.

To complete this configuration, you will need to create or modify an

access rule in “Access Control”. To modify an existing rule, click the

Edit option next to the rule you want to modify. To create a new rule,

click on the Add PC option.

From the Access Control Page, Add PC section, check the option for

“WWW with URL Blocking” in the Client PC Service table to filter out

the web sites and keywords selected below, on a specific PC.

The VoIP Router allows the user to block access to web sites from a

particular PC by entering either a full URL address or just a keyword.

This feature can be used to protect children from accessing violent or

pornographic web sites.

The following items are displayed on the Access Control screen:

Parameter Description

Enable Filtering:

Enables or disables the filtering function.

Normal Filtering Table:

Displays the IP address (or an IP address

range) filtering table.

Click Add PC on the Access Control screen to view the following

page.

Access Control Add PC

The settings in the screen shot below will block all email sending and

receiving.

Define the appropriate settings for client PC services (as shown

above). Click “OK” to save your settings. The added PC will now

appear in the Access Control page.

MAC Filter

Use this page to block access to your network using MAC addresses.

Edit Schedule Rule

You can create and edit schedule rules on this page.

Define the appropriate settings for a schedule rule (as shown on the

above screen).

Intrusion Detection

The VoIP Router’s firewall inspects packets at the application layer,

maintains TCP and UDP session information including timeouts and

number of active sessions, and provides the ability to detect and

prevent certain types of network attacks such as Denial-of-Service

(DoS) attacks.

Schedule Rule

You may filter Internet access for local clients based on rules.

Each access control rule may be activated at a scheduled time.

Define the schedule on the Schedule Rule page, and apply the rule on

the Access Control page.

Click Add Schedule Rule to add a new rule and bring up the following

page.
