DESCRIPTION
Select this option to have the NSA get IP address information
automatically.
If no IP address information is assigned, the NSA uses Auto-IP to
assign itself an IP address and subnet mask. For example, you could
connect the NSA directly to your computer. If the computer is also
set to get an IP address automatically, the computer and the NSA will
choose addresses for themselves and be able to communicate.
Select this option for the NSA to use fixed TCP/IP information. You
must fill in the following fields.
Type an IP address in this field.
Type a default gateway address in this field.
DNS (Domain Name System) is for mapping a domain name to its
corresponding IP address and vice versa. If you have the IP
address(es) of the DNS server(s), enter them.
Select the option to have the NSA get a DNS server address
automatically.
Select this option to choose a static DNS server address. Type the
DNS server IP address(es) into the fields below.
Type a primary DNS server IP address.
Type a secondary DNS server IP address.
Select this to configure an additional HTTP port for accessing the web
configurator. Specify a number in the Port Number field.
Jumbo frames improve network performance. You must have a 1
Gbps (Gigabit Ethernet) network that supports jumbo frames. Select
the largest size of frame that all of your network devices (including
computer Ethernet cards and switches, hubs, or routers) support.
When enabled, you can choose between 4 KB, 8 KB, and 9 KB frame
sizes.
Note: If you enable jumbo frames on the NSA in a network that
does not support them, you will lose access to the NSA. If
this occurs, you will have to restore the factory default
configuration. Push the RESET button on the NSA's rear
panel and release it after you hear a beep.
