DHCP lease time: Specify the time that a network device can lease a private IP address before the ADSL Router
reassigning the IP address.
Default Gateway: You check the Report this host as the default gateway box to use this host as the default
gateway or fill in an IP address as the default gateway.
Domain Name Servers: You can check the Report this host as the DNS server box to use this host as the default
DNS. Or you can uncheck the box and manually set up the DNS IP address in the
Primary/Secondary DNS IP address fields. The DNS server addresses will be passed to the
DHCP clients along with the IP addresses. The DHCP clients use the DNS to map a domain
name to its corresponding IP address and vice versa.
