Пакет dhcp-relay: Информация

The Internet Software Consortium DHCP Relay Agent, dhcrelay, provides a
means for relaying DHCP and BOOTP requests from a subnet to which no
DHCP server is directly connected to one or more DHCP servers on other
subnets.

You will have to define the environment variable SERVERS and optionally
OPTIONS in /etc/sysconfig/dhcrelay before starting the server.
