Traffic Redirect; Figure 6-7 Traffic Redirect Setup Example - ZyXEL Communications ZYWALL2 ET 2WE User Manual

ZyWALL 2 Series User's Guide
The MAC address screen allows users to configure the WAN port's MAC Address by either using the factory
default or cloning the MAC address from a computer on your LAN. Choose Factory Default to select the
factory assigned default MAC Address.
Otherwise, click Spoof this computer's MAC address - IP Address and enter the IP address of the
computer on the LAN whose MAC you are cloning. Once it is successfully configured, the address will be
copied to the rom file (configuration file). It will not change unless you change the setting or upload a
different ROM file.

Traffic Redirect

Traffic redirect forwards traffic to a backup gateway when the ZyWALL cannot connect to the Internet. An
example is shown in the figure below.

Figure 6-7 Traffic Redirect Setup Example

The following network topology allows you to avoid triangle route security issues when the backup gateway
is connected to the LAN. Use IP alias to configure the LAN into two or three logical networks with the
ZyWALL itself as the gateway for each LAN. Put the protected LAN in one subnet (Subnet 1 in the
following figure) and the backup gateway in another subnet (Subnet 2). Configure filters that allow packets
from the protected LAN (Subnet 1) to the backup gateway (Subnet 2).
