DHCP Overview

Network > DHCP

A firewall acting as a DHCP client (host) can request an IP address and other configuration settings from a DHCP server. Users on client firewalls save configuration time and effort, and need not know the addressing plan of the network or other network resources and options inherited from the DHCP server.
A firewall acting as a DHCP server can service clients. By using one of the DHCP addressing mechanisms, the administrator saves configuration time and has the benefit of reusing a limited number of IP addresses clients no longer need network connectivity. The server can also deliver IP addressing and DHCP options to multiple clients.
A firewall acting as a DHCP relay agent listens for broadcast and unicast DHCP messages and relays them between DHCP clients and servers.
