User Manual

However, using a large packet size becomes inefficient if an error occurs during transmission.That is because
if any part of a large packet is corrupt, the entire large packet must be resent. If you use a smaller MTU,
smaller packets are resent if a communication error occurs.
Your ReadyNAS system supports at least a maximum MTU size of 9214 bytes. (Some models support 9216
bytes.) Use this MTU size only if all components of your network, for example, network interface cards
(NICs), hosts, and your switch, support packets of this size or larger. Also MTU sizes greater than the default
can affect services such as ReadyCLOUD, ReadyNAS Replicate, and potentially Amazon Cloud.
DNS
DNS is short for Domain Name System. Because IP addresses are strings of numbers, they are hard to
remember. It is easier to remember a name (for example, www.netgear.com) than a string of numbers when
you want to visit a website. A DNS server translates IP addresses into website names and website names
into IP addresses.
If you selected the option to assign an IP address automatically when you configured your Ethernet settings,
the DNS fields are populated with the DNS settings from your DHCP server and cannot be edited.
If you selected the option to assign an IP address manually when you configured your Ethernet settings,
you must manually specify the IP addresses of the DNS servers and the domain name to access your
ReadyNAS system over the Internet.Your network administrator can help you determine your Domain Name
Server IP address.
Configure the Ethernet Interfaces
All ReadyNAS systems provide at least one physical Ethernet interface.
On ReadyNAS systems with two or more Ethernet interfaces, the interfaces can be used independently as
individual links or combined into a bonded adapter. Bonding can provide redundancy or increased throughput.
For each Ethernet interface, you can configure the following settings:
• MTU
• IPv4 settings including DNS servers
• IPv6 settings including DNS servers
The following table shows the default network configuration.
