Section 3 - Software Configuration
The following parameters will be available for configuration:
Enable DHCP
Server:
Check this box to enable the DHCP server on your router.
Uncheck to disable this function.
DHCP IP Address
Range:
Enter the starting and ending IP addresses for the DHCP
server’s IP assignment.
DHCP Lease
Time:
The length of time for the IP address lease. Enter the Lease
time in minutes.
Always
Broadcast:
If all the computers on the LAN successfully obtain 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
announcement:
Check this box to allow the DHCP Server to offer 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
from WAN:
If NetBIOS announcement is switched on, it will cause WINS information to be learned from the WAN side, if available. Turn 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.
NetBIOS node
type:
This field indicates how network hosts are to perform NetBIOS name registration and discovery. H-Node, this indicates a Hybrid-State of operation.
First WINS servers are tried, if any, followed by local network broadcast. This is generally the preferred mode if you have configured WINS servers.
M-Node (default), this indicates a Mixed-Mode of operation. First Broadcast operation is performed to register hosts and discover other hosts, if
broadcast operation fails, WINS servers are tried, if any. This mode favours broadcast operation which may be preferred if WINS servers are reachable
by a slow network link and the majority of network services such as servers and printers are local to the LAN. P-Node, this indicates to use WINS
servers ONLY. This setting is useful to force all NetBIOS operation to the configured WINS servers. You must have configured at least the primary
WINS server IP to point to a working WINS server. B-Node, this indicates to use local network broadcast ONLY. This setting is useful where there are
no WINS servers available, however, it is preferred you try M-Node operation first. This setting has no effect if the ‘Learn NetBIOS information from
WAN’ is activated.
