 **Normal** If the DHCP client on the LAN doesn't ask for a particular time value, this is the lease time used.
 **Maximum** If the DHCP client on the LAN asks for longer time than this, this is the lease time used. If a shorter time is requested by the client, it is granted.

 **Option** Number according to [[http://tools.ietf.org/html/rfc2132|RFC2132]], along with identification (the ISC DHCP server standard names).
 **Data** The data for the option. Typically an IP address in dot notation, a string or a number, depending on the option. Some options (no. 19,20,27,29,30,31,34,36,39) are flags - write "true" or "false" for these. For arrays of values (e.g. "time-servers") use comma as separator.
+**Allow DHCP client to set option 43** Uncheck this box if the automatic option 43 setting by the DHCP client is not wanted (see below, under [[dhcp_server#DHCP Client|DHCP Client]]).
