Network Security with pfSense

DHCP or DNS server

pfSense can act as a DNS server or DHCP server. DHCP is a communications protocol that network administrators use to centrally manage and automate the network configuration of devices attaching to an IP network. It removes the need to manually configure IP addresses and automatically assigns an IP address to a device, even when moving to different locations. DHCP is supported for both IPv4 and IPv6, that is, the Internet Protocol version. With the use of DHCP and domain name resolution all on the firewall, it makes life easier for configuring the network traffic precisely the way you need it.
