DNS Client
The DNS Client is used to resolve names of management servers within the operator’s management domain (see
Figure 30). This feature allows hostname configuration for NTP servers, Authorization Servers, DHCP relay
servers, and SNMP trap servers. Operators may choose to either enter in the FQDN (Fully Qualified Domain
Name) for the host name or to manually enter the IP addresses of the servers
.

Network Address Translation (NAT)
NAT, DHCP Server, DHCP Client, and DMZ in SM
The system provides NAT (network address translation) for SMs in the following combinations of NAT and
DHCP (Dynamic Host Configuration Protocol):
NAT Disabled
NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface) and DHCP Server
NAT with DHCP Client(DHCP selected as the Connection Type of the WAN interface)
NAT with DHCP Server
NAT without DHCP
NAT
NAT isolates devices connected to the Ethernet/wired side of an SM from being seen directly from the wireless
side of the SM. With NAT enabled, the SM has an IP address for transport traffic (separate from its address for
management), terminates transport traffic, and allows you to assign a range of IP addresses to devices that are
connected to the Ethernet/wired side of the SM.
