ddns-update-style none;
log-facility local7;
deny unknown-clients;
non-authoritative;
option subnet-mask 255.255.255.0;
default-lease-time 600;
max-lease-time 7200;
option ip-forwarding    false;  # No IP forwarding
option mask-supplier    false;  # Don't respond to ICMP Mask req
server-name "dhcp209";
next-server 192.168.0.100;

subnet 192.168.0.0 netmask 255.255.255.0 {
  range 192.168.0.1 192.168.0.88;
  option routers 192.168.0.100;
}

host rhelclient {
  next-server 192.168.0.100;
  filename "linux-install/lpxelinux.0";
  server-name "dhcp209";
  hardware ethernet 08:00:27:E7:34:E9;
  fixed-address 192.168.0.88;
}

The dhcp server has two network interfaces. Eth0 -public, Eth1-Private.
Eth1 is 192.168.0.100 and dhcpd is tied only to Eth1.
I just realized the /etc/hosts has dhcp209 pointed to Eth0's IP address.
Hope now this is not a major issue. Everything has been always like this on
tftp/dhcp server.

Thanks.
