Field Name Sample value Explanation
1. Disable Checked/unchecked Check to DISABLE the DHCP server.
2. Start 100 The starting address of the range that the DHCP server can use to give out to
devices. E.g.: if your LAN IP is 192.168.2.1 and your subnet mask is
255.255.255.0 that means that in your network a valid IP address has to be in
the range of [192.168.2.1 – 192.168.2.254](192.168.2.0 and 192.168.2.255
are special unavailable addresses). If the Start value is set to 100 then the
DHCP server will only be able to lease out addresses starting from
192.168.2.100
3. Limit 150 How many addresses the DHCP server gets to lease out. Continuing on the
above example: if the start address is 192.168.2.100 then the end address
will be 192.168.2.254 (100 + 150 – 1 = 254).
4. Lease time 12h How long can a leased IP be considered valid. An IP address after the
specified amount of time will expire and the device that leased it out will
have to request for a new one.
Advanced settings
You can also define some advanced options that specify how the DHCP server will operate on your LAN network.
Field Name Sample Value Explanation
1. Dynamic DHCP Checked/Unchecked Dynamically allocate client addresses, if set to 0 only clients present in
the ethers files are served
2. Force Checked/Unchecked Forces DHCP serving even if another DHCP server is detected on the
same network segment.
3. IPv4 netmask 255.255.255.0 You can override your LAN netmask here to make the DHCP server
think it’s serving a larger or a smaller network than it actually is.
