or another network device. Use this option if your ATA connects to one
network on the WAN port (10.0.0.0 for example) and to another network on
the LAN port (192.168.0.0 for example). This option is selected by default
and is suitable for most deployments.

another router. Choose this option if your ATA bridges a network (10.0.0.0 for
example) to its LAN port (with connected devices also in the 10.0.0x range).
