WAN-Wide Area Network

A WAN (Wide Area Network) is a computer network that covers a broad geographical area (eg.

Internet) that is used to connect LAN and other types of network systems.

WAN Service

Three WAN interfaces are provided for WAN connection: ADSL, VDSL and 3G/4G/LTE

Click Add to add new WAN connections.

There are three transfer modes for you to configure for WAN connection, namely ATM (ADSL), PTM

(VDSL) and 3G/LTE. Configuration of PTM mode is similar as ATM mode, here take ATM mode WAN

configuration for example

57

A) DSL

PPPoE

PPPoE (PPP over Ethernet) provides access control in a manner which is similar to dial-up services

using PPP.

VCI/VPI

: Enter the VCI/VPI combination from you ISP.

Encapsulation Mode

: Select the encapsulation mode, LLC/SNAP-BRIDGING, or VC/MUX.

Description

: User-defined description for the connection, commonly for friendly use.

802.1P Priority

: The parameter indicates the frame priority level from 0 owest) to 7 (highest), which

can be used to prioritize different classes of traffic (voice, video, data, etc). Enter the priority

identification, tagged: 0-1, untagged: -1.

Q VLAN ID

: It is a parameter to specify the VLAN which the frame belongs. Enter the VLAN ID

identification, tagged: 0-4094, untagged: -1.

Username

: Enter the account obtained from the ISP.

Password

: Enter the password obtained from the ISP.

Service Name

: The item is for identification purpose, user can define it yourself.

Authentication Method

: Default is Auto. Or else your ISP will advise you the appropriate mode.

Firewall

: Enable to drop all traffic from WAN side. If enabled, all incoming packets by default would be

dropped, and please turn to IP Filtering Incoming to add allowing rules.

NAT

: The NAT (Network Address Translation) feature allows multiple users to access the Internet

through a single IP account by sharing the single IP address. If users on your LAN have their own

public IP addresses to access the Internet, NAT function can be disabled. When enabled, a Fullcone

NAT parameter will appear, you can determine whether to enable Fullcone NAT. While only NAT

enabled, the default NAT type Port-Restricted cone NAT will be used.

Fullcone NAT

: Enable or disable fullcone NAT. Fullcone is a kind of NAT, in this mode, all requests

from the same internal IP address and port are mapped to the same external IP address and port.

58

Furthermore, any external host can send a packet to the internal host by sending a packet to the

mapped external address.

Note

: In PPPoE connection, NAT is enabled by default, you can determine whether to enable Fullcone

NAT or disable Fullcone NAT and only use NAT, the default NAT type is Port Restricted cone NAT. Of

Port-Restricted cone NAT, the restriction includes port numbers. Specifically, an external host can

send a packet, with source IP address X and source port P, to the internal host only if the internal host

had previously sent a packet to IP address X and port P.

IPv4 Address

: Select whether to set static IPv4 address or obtain automatically.

IP Address

: If Static is enabled in the above field, enter the static IPv4 address get from the ISP.

Dial on demand

: It is a parameter to let users to dial for connection to internet themselves. It is useful

when saving internet fees.

Inactivity Timeout

: The set Inactivity timeout period, unit: minutes. It is combined use with Dial on

Demand, users should specify the concrete time interval for dial on demand.

Obtain DNS:

I

Available WAN interfaces

: Select a desirable WAN interface as the IPv4 DNS server.

I

Static DNS Address

: To specify DNS server manually by entering your primary and

secondary DNS server addresses.

I

Parental Controls

: If user registers and gets a DNS account in the parental control

provider website, expecting to enjoy a more reliable and safer internet surfing

environment, please select this option (need to configure at Parental Control Provider).

Primary IPv4 DNS / Secondary IPv4 DNS

: Type the specific primary and secondary IPv4 DNS

Server address.

IPv6 for this service

: Enable to use IPv6 service.

IPv6 Address

: Select whether to set static IPv6 address or obtain automatically.

IP Address

: If Static is enabled in the above field, enter the static IPv6 address.

environment, please select this option (need to configure at Parental Control Provider).

Primary IPv6 DNS Server / Secondary IPv6 DNS Server

: Type the specific primary and secondary

IPv4 DNS Server address.

MTU

:

Maximum Transmission Unit, the size of the largest datagram (excluding media-specific

headers) that IP will attempt to send through the interface.

PPPoE with Pass-through

: Enable or disable PPPoE pass-through. If it is enabled, PCs behind the

router can dial itself.

IGMP Multicast Proxy

: Check whether to enable this feature. IGMP (Internet Group Management

Protocol) Proxy intercepts the IGMP request from Clients and set up the multicast-forwarding table, it

takes over some of the router’s job, simplifying the router’s job and multicast communication.

MLD Multicast Proxy

: check whether to enable this function. MLD (Multicast Listener Discovery

Protocol) Proxy intercepts the MLD request from Clients a set up the multicast-forwarding table. it

takes over some of the router’s job, simplifying the router’s job and multicast communication. Support

MLDv1 and MLDv2.

Here you can configure WAN Service, if it is OK, you can access the internet. You can go to Status

> WAN or Summary to view the WAN connection information (if your ISP provides IPv6 service, then

you will obtain an IPv6 address).
