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 (ZyNOS configuration file). It will not change unless
you change the setting or upload a different ROM file.
It is recommended that you clone the MAC
address prior to hooking up the WAN Port.
8.7 Traffic Redirect
Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect
to the Internet through its normal gateway. Connect the backup gateway on the WAN so that
the Prestige still provides firewall protection.
Figure 53 Traffic Redirect WAN Setup
The following network topology allows you to avoid triangle route security issues (see the
Appendices) when the backup gateway is connected to the LAN. Use IP alias to configure the
LAN into two or three logical networks with the Prestige 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/Prestige firewall rule
that forwards packets from the protected LAN (Subnet 1) to the backup gateway (Subnet 2).
