In DHCP server all this parameters (like DNS, GW, Netmask) have to be
configure first. if you want to set the default options
for GW and DNS then please do the changes in DHCP server like below.

Here is the example of dhcpd.conf file,

#
#   DHCP Server Config File
#
ddns-update-style none;
ignore client-updates;

lease-file-name "/var/lib/dhcpd/dhcpd.leases";
authoritative;

option domain-name                      "example.com";
default-lease-time                      86400;   # 24 hours
max-lease-time                          172800;  # 48 hours

subnet 192.168.1.0 netmask 255.255.255.0 {
        option routers                  192.168.1.1;
        option subnet-mask              255.255.255.0;
        option broadcast-address        192.168.1.255;
        option domain-name-servers      192.168.1.1;
        option ntp-servers              192.168.1.1;
        range   192.168.1.101   192.168.1.200;
}
