<td>DHCP</td>
<td>Enable {{!}} Disable {{!}} DHCP Relay; Default: '''Enable'''</td>

<td>Start</td>
<td>integer [1..253]; Default: '''100'''</td>
<td>The starting IP address value. e.g., if your router’s 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 [192.168.2.0..192.168.2.254] (192.168.2.255 is a special unavailable address). If the Start value is set to 100 then the DHCP server will only lease out addresses starting from 192.168.2.100</td>
</tr>
<tr>
<td>Limit</td>
<td>integer [1..4294967296]; Default: '''150'''</td>
<td>How many addresses the DHCP server can lease out. Continuing from the above example: if the start address is 192.168.2.100 and the server can lease out 150 (default limit value), availabe addresses will be from 192.168.2.100 to 192.168.2.249 (100 + 150 – 1 = 249; this is because the first address is inclusive)</td>

<td>Lease time</td>
<td>time in 'h' (hours) or 'm' (minutes); Default: '''12h'''</td>
<td>he duration of an IP lease. Leased out addresses will expire after the amount of time specified in this field and the device that was using the lease will have to request a new DHCP lease. However, if the device stays connected, its lease will be renewed after half of the specified amount of time passes, e.g., if the lease time is 12 hours, then every 6 hours the device will send a request to the DHCP server asking to renew its lease
Lease time can be set in '''hours''' ('''h''') or '''minutes''' ('''m'''). The minimal amount of time that can be specified is '''2min''' ('''2m''')</td>

You may also apply more complicated, less common configurations to your router's DHCP Server in the Advanced Settings tab. For example, you can apply virtually any custom DHCP configuration by typing in optional commands in the DHCP Options field.

<td>yes {{!}} no; Default: '''no'''</td>
<td>The DHCP force function ensures that the router will always start it’s DHCP server, even if there is another DHCP server already running in the router’s network.

As you can see, the configuration is very similar to the static protocol; in the example above an IP address with a 99th subnet is defined. In this case, if some device has an IP in the 99th subnet (e.g., 192.168.99.xxx) and the subnet’s gateway metric is “higher” and the device is trying to reach the internet it will reroute it’s traffic not to the gateway that is defined in common configurations but through the one that is specified in IP aliases.
