Multi WAN Setting Guide

Date:2018-01-16
1. Overview

Multi WAN is used to realize the distribution of different kinds of services, and Device’s Multi WAN supports the distribution of data services, voice services and management services. By setting different VLANs, different kinds of data should be distributed to the corresponding network, for example, INTERNET and Other VLAN supports data transmission, VOICE VLAN supports voice transmission and TR069 VLAN supports WEB, telnet and TR069 services transmission.

There are severals advanced function on Multi WAN setting:
PPPoE Bridge could allow PPPoE packets pass, which could avoid L2 packets flood to LAN ports.
HW Bridge could work like L2 Switch to increase throughput between WAN and LAN.
Vlan Trunk could allow tagged packets be switch to LAN ports directly.
IPTV could be supported with Other VLAN binded LAN ports.

2. Setting up the Internet Connection

From WAN page, multi wan connection could be built or deteted. Under is default configuration of WAN.

2.1 Connect Name and Service

Connect Name Table is as below:

ContentDefineComment
No1~99WAN Connection id
ServiceTR069The connection only support management application, like TR069, WEB, SNMP and Provision
 INTERNETThe connection only support internet service
 TR069_INTERNETThe connection support management and internet application
 VOICEThe connection only support voice application, like sip and rtp
 TR069_VOICEThe connection support both management and voice application
 VOICE_INTERNETThe connection support voice and internet application
 TR069_VOICE_INTERNETThe connection support management, voice and internet application
 OtherThe connection support STB
NAT ModeBBridge

VLAN IDVIDVLAN ID

For example:
1_TR069_R_VID_2 (First Interface, Service is TR069, NAT Mode, VLAN ID is 2)
2_INTERNET_B_VID_(Second Interface, Service is INTERNET, Bridge Mode, VLAN is disabled)

2.2 Bridge Mode

Bridge Mode under Multi WAN is different with traditional bridge setting. Bridge mode has no ip address and only work as a bridge between WAN port and LAN port. So Route Connection has to be build to give ip address to local service on device.
Under is example of bridge mode:
1_TR069_VOICE_INTERNET_R_VID_ is router connection for local service.
2_Other_B_VID_ is bridge connection for host of LAN port.

If bridge setting is complex, please refer to next section for fast setting of bridge mode.

Bridge Type:
Bridge TypeComment
IP BridgeAllow all ethernet packets pass. PC could connect to upper network directly.
PPPoE BridgeOnly Allow PPPoE packets pass. PC need PPPoE dial-up software.
Hardware IP BridgePackets pass through hardware switch with wired speed. Do not support wireless port bind.

DHCP Service Type:
DHCP Service TypeComment
Pass ThroughDhcp packets can be forwarded between WAN and LAN, dhcp server in gateway will not allocate IP to hosts of LAN port.
DHCP SnoopingWhen gateway forwards dhcp packets form LAN to WAN it will add option82 to dhcp packet, and it will remove option82 when forward dhcp packet form WAN to LAN. Local dhcp service will not allocate ip to hosts of LAN port.
Local ServiceGateway will not forward dhcp packets between Lan and Wan, it also block dhcp packet from WAN port. Hosts of LAN port can get ip from dhcp server run in gateway.

VLAN Mode:
VLAN ModeComment
DisableThe WAN interface is untagged. LAN is untagged.
EnableThe WAN interface is tagged. LAN is untagged.
TrunkOnly valid in bridge mode. All ports, include WAN and LAN, belong to this VLAN Id and all ports are tagged in this VLAN id. Tagged packets could pass through WAN and LAN.

3. Fast Bridge Setting

Step 1: Login WEB of Device.Turn to Page Administration->Operating Mode. Set Operating mode to Basic Mode. Save.
