IP address - 192.168.10.2
# to access by computer in your local network

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">

    <key>bootp_enabled</key>
    <false/>
    <key>detect_other_dhcp_server</key>
    <integer>1</integer>
    <key>dhcp_enabled</key>
    <array>

            <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>
