11: Network LAN Interface Network > Interface > LAN This page allows you to configure the LAN interface. The LAN interface should use Static Address. Gateway may be used but is not required. DHCP server may be used to dynamically assign an IP address to clients connecting to the LAN. If DHCP server is disabled for the interface, all the LAN devices connected to the gateway should have a static LAN IP configured. DHCP Server The G520 series gateway can act as the DHCP server and assign IP addresses to devices connecting to the LAN network. The DHCP server maintains a database of available IP addresses and configuration information. When it receives a request from a client, the DHCP server determines the network to which the DHCP client is connected, allocates an IP address or prefix appropriate for the client, and sends configuration information appropriate for that client. DHCP servers typically grant IP addresses to clients for a limited interval called a lease. DHCP clients are responsible for renewing their IP address before that interval has expired, and must stop using the address once the interval has expired, if they have not been able to renew it. DHCP is used for IPv4 and IPv6. While both versions serve the same purpose, the details of the protocol for IPv4 and IPv6 are sufficiently different that they should be considered separate protocols. Interface configuration settings are determined mainly by the protocol selection. For a description of the protocol settings, see Static Address. To edit the interface: 1. Go to Network > Interfaces, select LAN and click Edit. G520 Series IoT Cellular Gateway User Guide 153
