Arch Linux - Setup dhcp daemon for local network

I want to setup a dhcp server for my local test network, here is  network scenario:
  1. usb0 - my internet access point connect to my WiMax box.(192.168.1.x)
  2. eth0 - my local testing network.(192.168.10.x)
Step 1. bind ip address to eth0

ifconfig eth0

Step 2. install required packages

pacman -S dhcp

Step 3. edit /etc/dhcpd.conf (remove all default dhcpd.conf)

# dhcp.conf
subnet netmask {
  option domain-name-servers,;
  option routers;
  option subnet-mask;
  option broadcast-address;
  default-lease-time 600;
  max-lease-time 7200;
  range dynamic-bootp;

Step 4. start service

systemctl start dhcpd4
