A DHCP relay agent
dhcp-helper is a DHCP and BOOTP relay agent. It listens for DHCP
and BOOTP broadcasts on directly connected subnets and relays
them to DHCP or BOOTP servers elsewhere. dhcp-helper is much smaller
than dhcp3-relay package and it does not require the Packet Filter
kernel facility to be present. This makes it a good choice for use
on small or embedded systems. Unlike dhcp3-relay, dhcp-helper can be
configured to forward DHCP requests as broadcasts, and therefore does
not need to be given the IP address of the DHCP server, only the
network in which it resides.
