Section 3 - Software Configuration
The following parameters will be available for configuration:
Enable DHCP Check this box to enable the DHCP server on your
Server: router. Uncheck to disable this function.
DHCP IP Address
Enter the starting and ending IP addresses for the
Range:
DHCP server's IP assignment.
DHCP Lease The length of time for the IP address lease. Enter
Time: the Lease time in minutes.
Always If all the computers on the LAN successfully obtain
Broadcast: their IP addresses from the router's DHCP server
as expected, this option can remain disabled.
However, if one of the computers on the LAN
fails to obtain an IP address from the router's
DHCP server, it may have an old DHCP client that
incorrectly turns off the broadcast flag of DHCP
packets. Enabling this option will cause the router
to always broadcast its responses to all clients,
thereby working around the problem, at the cost
of increased broadcast traffic on the LAN.
NetBIOS Check this box to allow the DHCP Server to offer
announcement: NetBIOS configuration settings to the LAN hosts.
NetBIOS allow LAN hosts to discover all other
computers within the network, e.g. within Network
Neighborhood.
Learn NetBIOS
If NetBIOS announcement is switched on, it will cause WINS information to be learned from the WAN side, if available. Turn
from WAN:
this setting off to configure manually.
NetBIOS Scope:
This is an advanced setting and is normally left blank. This allows the configuration of a NetBIOS 'domain' name under which
network hosts operate. This setting has no effect if the 'Learn NetBIOS information from WAN' is activated.
