Configuring DHCP
Dynamic Host Configuration Protocol (DHCP) allows for dynamic allocation of network addresses
and configuration to newly attached hosts. The gateway can be both a DHCP client and DHCP
server. The gateway acts as a client when it communicates to your service provider over the
Internet using DHCP. For this communication, you cannot modify the related DHCP settings. The
gateway is a DHCP server to your local network devices such as the computers connecting to it.
Note If you change the local network IP address range, you must renew the DHCP lease on all
devices on the gateway’s local network and manually reconfigure all devices configured
with static IP addresses.
