3. DHCP Server
The DHCP server function makes setting up a network very easy by
assigning IP addresses to each computer on the network automatically.
The default setting is “On”. The DHCP server can be turned OFF if
necessary; however, in order to do so you must manually set a static
IP address for each computer on your network. To turn off the DHCP
server, select “Off” and click “Apply Changes”.
4. IP Pool
The range of IP addresses set aside for dynamic assignment to the
computers on your network. The default is 2–100 (99 computers). If you
want to change this number, you can do so by entering a new starting
and ending IP address and clicking on “Apply Changes”. The DHCP server
can assign 100 IP addresses automatically. This means that you cannot
specify an IP address pool larger than 100 computers. For example,
starting at 50 means you have to end at 150 or lower so as not to
exceed the 100-client limit. The starting IP address must be lower in
number than the ending IP address.
5. Lease Time
The length of time the DHCP server will reserve the IP address for
each computer. We recommend that you leave the lease time set to
“Forever”. The default setting is “Forever”, meaning that any time a
computer is assigned an IP address by the DHCP server, the IP address
will not change for that particular computer. Setting lease times
for shorter intervals such as one day or one hour frees IP addresses
after the specified period of time. This also means that a particular
computer’s IP address may change over time. If you have set any of the
other advanced features of the Router such as DMZ or client IP filters,
these are dependent on the IP address. For this reason, you will not
want the IP address to change.
6. Local Domain Name
The default setting is “Ativa”. You can set a local domain name (network
name) for your network. It is not necessary to change this setting unless
you have a specific naming requirement. You can name the network
anything you want such as “MY NETWORK”.
