LAN IP Setup

The LAN IP screen allows you to configure LAN services such as the IP address of the gateway and DHCP. The TCP/IP and DHCP default values work fine in most cases.

Note: If you disable the DHCP server, you will need to assign to your computer a static IP address to reconnect to the gateway and enable the DHCP server again.

To configure LAN IP settings:

1.In the main menu, under Advanced, select

LAN IP.

2.Specify these settings:

•LAN IP Address: The factory default setting is 192.168.0.1.

•Subnet Mask: The network number portion of an IP address. Unless you are implementing subnetting, use 255.255.255.0 as the subnet mask.

•DHCP Server: The Yes radio button is selected by default so the gateway acts as a DHCP server, providing the TCP/IP configuration for all the computers connected to it.

If you will assign IP addresses manually, or you have another DHCP server on your network, select the No radio button.

•Starting IP Address and Ending IP Address: These fields specify the range in the IP address pool.

•Max Users: The maximum number of users on the network.

•DHCP Lease: See the following section, Reserving an IP Address for DHCP Use.

3.Click Apply to save your LAN settings
