SANTIS ADSL 50/500 User Manual
The ADSL Router implements a built-in DHCP (Dynamic Host Configuration Protocol) server, which dynamically
assigns IP addresses and DNS server to the PCs on the LAN. DHCP function spares you the hassle of manually
assigning a fixed IP address to each PC on the LAN. It is probably you already have a DHCP server on your network
and you do not enable this function. By default the DHCP Server is enabled on private LAN interface (192.168.1.1).

First IP address of the DHCP address range.
Last IP address of the DHCP address range.
Specify the time that a network device can lease a private IP address before the ADSL
Router reassigning the IP address.
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.
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.
If the DHCP Relay Agent is activated, those DHCP Discover or Request packets
coming from the end users' PCs will be relayed to a remote end DHCP server which is
hosted by an Internet Service Provider (ISP). Some ISPs would like to be able to
distribute IP addresses to end user PCs directly.
