1. config your mac network enviroment

   # your ip address connect with the gateway at upper level
   IP address - 192.168.10.2
   # to access by computer in your local network
   Subnet Mask - 255.255.255.0

2. create /etc/bootpd.plist, configuration as follows:

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
   <key>bootp_enabled</key>
   <false/>
   <key>detect_other_dhcp_server</key>
   <integer>1</integer>
   <key>dhcp_enabled</key>
   <array>
       <string>en0</string>
   </array>
   <key>reply_threshold_seconds</key>
   <integer>0</integer>
   <key>Subnets</key>
   <array>
       <dict>
           <key>allocate</key>
           <true/>
           <key>dhcp_router</key>
           <string>192.168.10.1</string>
           <key>lease_max</key>
           <integer>86400</integer>
           <key>lease_min</key>
           <integer>86400</integer>
           <key>name</key>
           <string>192.168.10</string>
           <key>net_address</key>
           <string>192.168.10.0</string>
           <key>net_mask</key>
           <string>255.255.255.0</string>
           <key>net_range</key>
           <array>
               <string>192.168.10.100</string>
               <string>192.168.10.200</string>
           </array>
       </dict>
   </array>
   </dict>
   </plist>
