LAN Settings 45

The LAN Settings screen is used to specify the LAN IP address of your

Gateway, and to configure the DHCP server.

1Select Unit Configuration and then specify the Gateway IP Address and Subnet Mask in the LAN Settings field. The default IP address of the Gateway is 192.168.1.1.

2If you want to use the Gateway as a DHCP Server, click in the Enable check box.

3Clicking Auto Range will automatically choose the largest available range of addresses for your network.

4Check all of your settings, and then click Apply.

The DHCP server will give out addresses to both wired and wireless clients.

DHCP Clients List Figure 32 DHCP Clients List Screen

The DHCP Clients List provides details on the devices that are connected to the LAN. The list is only created when the Gateway is set up as a DHCP server. For each device that is connected to the LAN, the IP address, Host Name, MAC address and Client Type of that device is displayed. As you connect more devices to the LAN, the client list will grow to a maximum number of clients, which is determined by the IP address range.

The Release button allows the lease time for the IP address that has been issued to a device to be cleared. The lease time is set at 12 hours. If a PC has been switched off, using the Release button would allow the 12 hour lease time to be cleared. The IP address would then be available for another device if there were no other IP addresses available.
