NBG410W3G Series User’s Guide

Traffic redirect forwards WAN traffic to a backup gateway when the ZyXEL Device cannot 
connect to the Internet through its normal gateway. Connect the backup gateway on the WAN 
so that the ZyXEL Device still provides firewall protection for the LAN. 

Figure 76   Traffic Redirect WAN Setup

IP alias allows you to avoid triangle route security issues when the backup gateway is 
connected to the LAN or DMZ. Use IP alias to configure the LAN into two or three logical 
networks with the ZyXEL Device itself as the gateway for each LAN network. Put the 
protected LAN in one subnet (Subnet 1 in the following figure) and the backup gateway in 
another subnet (Subnet 2). Configure a LAN to LAN/ZyXEL Device firewall rule that 
forwards packets from the protected LAN (Subnet 1) to the backup gateway (Subnet 2).

budget or % of 

data budget 

Specify the actions the ZyXEL Device takes when the specified percentage of time 

budget or data limit is exceeded. Enter a number from 1 to 99 in the percentage 

fields. If you change the value after you configure and enable budget control, the 

ZyXEL Device resets the statistics.
Select Log to create a log.
Select Alert to create an alert. This option is available only when you select Log.
If you select Log, you can also select recurring every to have the ZyXEL Device 

send a log (and alert if selected) for this event periodically. Specify how often (from 

1 to 65535 minutes) to send the log (and alert if selected).
