3.10.1.3 IP Address Mapping

Go to

Advanced Setup ->NAT -> Multiple ->IP Address mapping

to set IP

Address mapping parameters.

The IP Address Mapping is for those VCs that with multiple IPs. The IP Address

Mapping rule is per-VC based. (only for Multiple IPs’ VCs).

Rule Index:

The Virtual server rule index for this VC. You can specify up to 10

rules. All the VCs with single IP will use the same Virtual Server rules.

Rule Type:

There are 4 types of

One-to-One

,

Many-to-One, Many-to-Many Overload

,

52

and

Many-to Many No-Overload

.

Local Start & End IP:

Enter the local IP address you plan to map to. Local Start IP

is the starting local IP address & Local End IP is the ending local IP address. If the

rule is for all local IPs, then the Start IP is 0.0.0.0 and the End IP is 255.255.255.255.

Public Start & End IP:

Enter the Public IP Address you want to do NAT. Public

Start IP is the starting Public IP Address and Public End IP is the ending Public IP

Address. If you have a Dynamic IP, enter 0.0.0.0 as the Public Start IP.

ADSL Mode:

Select which mode your ADSL connection uses from the dropdown

list.

The option has Auto Sync-up, ADSL2+, ADSL2, G.DMT, T1.413, G.LITE

ADSL Type:

3.10.3 Routing

°

3.10.3.1 Static Routing

Go to

Advance Setup-> Routing

to see the Routing Table

Routing Table List

This table lists IP address of Internet destinations commonly accessed by your

network. When a computer requests to send data to a listed destination, the device

uses the Gateway IP to identify the first Internet router it should contact to route the

data most efficiently. Select this option will list the routing table information. You can

press

ADD ROUTE

to edit the static route. (As below screen)

[Static Route]

Select this option to set Static Routing information.

Destination IP Address:

This parameter specifies the IP network address of the final

destination of packets routed by this rule.

54

IP Subnet Mask:

Enter the subnet mask for this destination.

Gateway IP Address:

Enter the IP address of the gateway. A

gateway

does the actual

forwarding of the packets. Enter the gateway’s IP address in the field or select which

PVC you wish to act as a gateway.

The gateway is an immediate neighbor of your ADSL Router that will forward the

packet to the destination. On the LAN, the gateway must be a router on the same

segment as your Router; over Internet (WAN), the gateway must be the IP address of

one of the remote nodes.

Metric:

Metric represents the “cost” of transmission for routing purposes. IP Routing

uses hop count as the measurement of cost, with a minimum of 1 for directly

connected networks. Enter a number that approximates the cost for this link. The

number need not to be precise, but it must between 1 and 15. In practice, 2 or 3 is

usually a good number.

Announced in RIP:

This parameter determines if the ADSL router includes the

router to this remote node in its RIP broadcasts. If you choose

Yes

, the router in this

remote node will be propagated to other hosts through RIP broadcasts. If you choose

No

, this route is kept private and is not included in the RIP broadcasts.

3.10.3.2 Dynamic Routing

Go to

Interface Setup -> LAN

to select the Dynamic Route from

RIP1

,

RIP2-B

, and

RIP2-M

.

Explaining RIP Setup

Routing Information Protocol (RIP) allows a router to exchange routing

information with other routers. The RIP Direction field controls how RIP packets are

allowed to enter and leave the router. Selecting

Both

means the router will broadcast its

routing table and incorporate the RIP information that it receives. Selecting

In Only

means the router will only accept RIP packets received, not send RIP packets. Selecting

Out Only

means the router will only send RIP packets, not accept any RIP packets

received. Selecting

None

means the router will not send any RIP packets nor will it

accept any RIP packets received.

The Dynamic Route field controls the format and the broadcasting method of RIP

packets that the router sends. It recognizes both formats when receiving packets.

55

RIP-1

is universally supported, but

RIP-2

carries more information.

RIP-1

is adequate

for most networks. Only consider

RIP-2

if your network has unusual topology.

Both

RIP-2B

and

RIP-2M

sends the routing data in

RIP-2

format.

RIP-2B

uses subnet

broadcasting while

RIP-2M

uses multicasting.

Direction:

Select the RIP direction from

None

,

Both

,

In Only

and

Out Only

.

Multicast:

IGMP (Internet Group Multicast Protocol) is a session-layer protocol used

to establish membership in a multicast group. The ADSL router supports both

IGMP-v1

and

IGMP-v2.

Select

None

to disable it. Please refer to

Internet

²

Multicast

.

The only difference is the interface.

3.10.4 Firewall

Go to

Advance Setup

->

Firewall

to set firewall rule.

User can enable or disable firewall feature of the ADSL router in the page.
