You can configure the ATA to operate in one of the following modes:
• NAT: Network Address Translation (NAT) is a function that allows multiple
devices on a private network to share a public, routable IP address to
establish connections over the Internet. To enable Voice over IP service to
co-exist with NAT, some form of NAT traversal is required, either on the ATA
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. 1 68.0.0 for example).
• Bridge: Bridged mode is used if the ATA is acting as a bridge device to
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).
Description
The name of the ATA. The default value is the model
number. Your ISP may specify a host name to use.
The domain name, if specified by your ISP. Otherwise,
leave the field blank.
IP addresses for up to three DNS servers that DHCP
clients should use directly for name resolution. The
default entries are 0, in which case the ATA uses the DNS
servers that are specified for the WAN connection.
