Auto Sensing And Auto Uplink™ Lan Ethernet Connections; Protocol Support - NETGEAR MBR814X Reference Manual

Auto Sensing and Auto Uplink™ LAN Ethernet Connections
With its internal 4-port 10/100 switch, the MBR814X can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN ports are autosensing and
capable of full-duplex or half-duplex operation.
The router incorporates Auto Uplink
sense whether the Ethernet cable plugged into the port should have a 'normal' connection such as
to a computer or an 'uplink' connection such as to a switch or hub. That port will then configure
itself to the correct configuration. This feature also eliminates the need to worry about crossover
cables, as Auto Uplink will accommodate either type of cable to make the right connection.

Protocol Support

The MBR814X supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP). See the link to
Appendix B for further information on TCP/IP.
• The Ability to Enable or Disable IP Address Sharing by NAT
The MBR814X allows several networked PCs to share an Internet account using only a single IP
address, which may be statically or dynamically assigned by your Internet service provider
(ISP). This technique, known as Network Address Translation (NAT), allows the use of an
inexpensive single-user ISP account. This feature can also be turned off completely while
using the MBR814X if you want to manage the IP address scheme yourself.
• Automatic Configuration of Attached PCs by DHCP
The MBR814X dynamically assigns network configuration information, including IP, router,
and domain name server (DNS) addresses, to attached PCs on the LAN using the Dynamic
Host Configuration Protocol (DHCP). This feature greatly simplifies configuration of PCs on
your local network.
• DNS Proxy
When DHCP is enabled and no DNS addresses are specified, the router provides its own
address as a DNS server to the attached PCs. The router obtains actual DNS addresses from
the ISP during connection setup and forwards DNS requests from the LAN.
• Dynamic DNS
Dynamic DNS services allow remote users to find your network using a domain name when
your IP address is not permanently assigned. The router contains a client that can connect to
many popular Dynamic DNS services to register your dynamic IP address.
