 182 <li><b>Intercept DNS port</b> - Any DNS requests/packets sent out to UDP port 53 are redirected to the internal DNS server.</li>

 185 <li><b>Maximum active DHCP leases</b> - Self-explanatory.</li>
 186 <li><b>Static lease time</b> - Absolute maximum amount of time allowed for any DHCP lease to be valid.</li>
