Section 3 - Configuration LAN Setup To access the LAN Setup window, click the LAN Setup button in the Setup directory. You can configure the LAN IP address to suit your preference. Many users will find it convenient to use the default settings together with DHCP service to manage the IP settings for their private network. The IP address of the Modem is the base address used for DHCP. In order to use the Modem for DHCP on your LAN, the IP address pool used for DHCP must be compatible with the IP address of the Modem. The IP addresses available in the DHCP IP address pool will change automatically if you change the IP address of the Modem. See the next section for information on DHCP setup. To change the LAN Modem IP Address or Subnet Mask, type in the desired values in the Modem Settings section and click the Apply Settings button. Your web browser should automatically be redirected to the new IP address. You will be asked to login again to the Modem's web manager. The DHCP server is enabled by default for the Modem's Ethernet LAN interface. DHCP service will supply IP settings to workstations configured to automatically obtain IP settings that are connected to the Modem though the Ethernet port. When the Modem is used for DHCP it becomes the default gateway for DHCP client connected to it. Keep in mind that if you change the IP address of the Modem the range of IP addresses in the pool used for DHCP on the LAN will also be changed. The IP address pool can be up to 253 IP addresses. There are two options for DHCP service: • You can use the Modem as a DHCP server for your LAN. • You can disable DHCP service and manually configure IP settings for workstations.
