I have the following as my /etc/dhcpd.conf file:
# dhcpd.conf
option routers 192.168.1.1;
option domain-name "kwiqsilver.org";
option domain-name-servers 68.2.16.30, 68.1.208.30;

option subnet-mask 255.255.255.0;
default-lease-time 600;
max-lease-time 7200;

subnet 192.168.1.0 netmask 255.255.255.0 {
  range 192.168.1.101 192.168.1.200;
  option broadcast-address 192.168.1.255;
}
# dhcpd.conf

The clients can connect, but when I try to ping past the gateway I get
"Network is unreachable" errors.
