LAN Configuration

	input your network configuration.
IP	IP address of the WAN interface.
Netmask	Network mask, which is generally: 255.255.255.0
Gateway	Default Gateway IP address.
DNS Server	Domain Name Service (DNS) server IP address.
IP Sharing Mode	When enabled, PCs connected to the LAN port will be able to
	access the WAN. Default is Enabled.
Link Aggregation	Specifies whether WAN and LAN ports will be aggregated and
	act as one port.
	Failover: When one port fails, the other one will take over.
	Load Balance: Ethernet traffic will flow alternative between two
	Ethernet ports.

NOTE

•Only use Jumbo Frame settings when operating in a Gigabit environment where all other clients have Jumbo Frame Setting enabled.

•Enabling DHCP automatically turns on UPnP—see the Service Support Screen.

•If you are only using the WAN port, we suggest that you disable IP Sharing Mode. This will result in higher throughput.

•A correct DNS setting is vital to networks services, such as SMTP and NTP.

•To use the Link Aggregation feature, please make sure the networking equipment on the other end of Ethernet cable also supports 802.3ad protocol.

WARNING

Most Fast Ethernet (10/100) Switches/Routers do not support Jumbo Frame and you will not be able to connect to your 1U4500 after Jumbo Frame is turned on. If this happens, turn off the 1U4500. Then, power on the 1U4500 and immediately press and hold the Reset button on the back of the unit for 10 seconds. This will reset your network settings, password, and turn off Jumbo Frame Support.

The 1U4500 supports two Gigabit Ethernet ports for higher service availability. To configure these ports, choose LAN from the Network menu, and the LAN Configuration screen appears. Press Apply to save your changes.
