The INI file looks like this:
[General] SUBNETMASK=255.255.255.0 LEASETIME=32000000 ; approx. 1 year ROUTER_1=192.168.10.1 DNS_1=192.168.10.1 [Settings] IPBIND_1=192.168.10.1 IgnoreUnknownClients=1 [00-E0-00-1C-AB-68] ; Client 2 IPADDR=192.168.10.50 [00-E0-00-1C-AB-67] ; Client 1 IPADDR=192.168.10.11
Please note the line IgnoreUnknownClients=1. This option prevents the DHCP Server from sending answers to clients that are not configured in the INI file.
