 Chapter 5 WAN Setup

P-870HW-51a v2 User’s Guide

The ZyXEL Device allows you to configure more than one Internet access 
connection. To configure additional Internet access connections click Network > 
WAN > More Connections. The screen differs by the encapsulation you select. 

PPPoE 

Passthrough 

(PPPoE 

encapsulati

on only)

This field is available when you select PPPoE encapsulation. 

In addition to the ZyXEL Device's built-in PPPoE client, you can enable 
PPPoE pass through to allow up to ten hosts on the LAN to use PPPoE 
client software on their computers to connect to the ISP via the ZyXEL 
Device. Each host can have a separate account and a public WAN IP 
address. 

PPPoE pass through is an alternative to NAT for application where NAT is 
not appropriate.

Disable PPPoE pass through if you do not need to allow hosts on the LAN 
to use PPPoE client software on their computers to connect to the ISP.

IP Filter

This section is not available when you configure the ZyXEL Device to be 
in bridge mode.

IP Filter 

Active

Select this option to enable IP filtering on this connection.

VLAN

VLAN Active Select this option to enable VLAN multiplexing of multiple protocols over 

a single virtual circuit. You need to assign a VLAN ID and priority level to 
traffic through each WAN connection. All WAN connections share one 
MAC address. This allows the backbone switch to classify and service 
traffic based on the VLAN tag, instead of the MAC address.

Otherwise, disable VLAN multiplexing and each WAN connection has its 
own MAC address.

Note: This field is only configurable for the first WAN connection. 

When you change the setting here, all existing WAN 
connections will be removed except for the first WAN 
connection.

VLAN ID

Enter a VLAN ID number for traffic that goes through this connection.

Priority

Enter a priority level for traffic that goes through this connection.

Back
