Enable DHCP Server:

Once your device is properly configured and this option is

enabled, the DHCP Server function will assign your network devices the necessary

information to connect to the LAN and Internet. This eliminates the need to manually

configure each device on your network with IP settings. When you set the DHCP

server to

Enabled

, the following options appear.

Note: The devices on your network must have TCP/IP bound to the Ethernet

connection with the “DHCP” or “Obtain an IP address automatically” option enabled.

DHCP IP Address Range:

This option defines the range of addresses available for

the Router to assign to your internal network. If you have any devices using static IP

addresses, be sure the addresses do not fall within the range defined here. A Static

IP address is one that is entered in manually on the device. Also, the range must be

specified with the same 192.168.176–prefix as the Router IP Address.

Example: Your device uses an IP address of 192.168.176.1. You’ve assigned a

computer designated as a Web server with a static IP address of 192.168.176.3.

You’ve assigned another computer designated as an FTP server with a static IP

address of 192.168.176.4. The starting IP address for your DHCP server needs to be

192.168.176.5 or above.

DHCP Lease Time:

The amount of time a computer may have an IP address before

it is required to renew the lease. The lease functions just as a lease on an apartment

would. The initial lease designates the amount of time before the lease expires. If

the tenant wishes to retain the address when the lease expires then a new lease is

established. If the lease expires and the address is no longer needed, then another

tenant may use the address.

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.

Setting NetBIOS Advertisement to

Enabled

will reveal the following options.

Learn NetBIOS information from WAN:

If NetBIOS advertisement is switched on,

switching this setting on causes 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 Registration mode:

Indicates how network hosts are to perform NetBIOS

name registration and discovery.



Broadcast Only:

Indicates usage of 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.



Point-to-point:

Indicates usage of 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.



Mixed

(default):

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 favors 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.



Hybrid:

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.

Primary WINS Server IP Address:

Configure the IP address of the preferred

WINS server. WINS Servers store information regarding network hosts, allowing

hosts to 'register' themselves as well as discover other available hosts, e.g. for use in

Network Neighborhood. This setting has no effect if the 'Learn NetBIOS information

from WAN' is activated.

Secondary WINS Server IP Address:

Configure the IP address of the backup

WINS server, if any. This setting has no effect if the 'Learn NetBIOS information from

WAN' is activated.

2.2.4

Add DHCP Reservation

This option lets you reserve IP addresses, and assign the same IP address to the

network device with the specified MAC address any time it requests an IP address.

This is almost the same as when a device (like your computer) has a static IP

address except that the device must still request an IP address from this device. This

Page 17 of 92

Page 18 / 92

device will provide the other device (ex: your computer) the same IP address every

time. DHCP Reservations are helpful for server computers on the local network that

are hosting applications such as Web and FTP. Servers on your network should either

use a static IP address or use this option.

Computer name:

You can assign a name for each computer that is given a reserved

IP address. This may help you keep track of which computers are assigned this way.

Example: Game Server.

IP Address:

The LAN address that you want to reserve. The IP address must have

the same “prefix” as the Router IP Address (usually 192.168.176).

MAC Address:

The MAC address of the device that will receive the reserved IP. A

MAC address is usually located on a sticker on the bottom of a network device. The

MAC address is comprised of twelve digits. Each pair of hexadecimal digits are

usually separated by dashes or colons such as 00-0D-88-11-22-33 or

00:0D:88:11:22:33. If your network device is a computer and the network card is

already located inside the computer, you can connect to the RGW208EN from the

computer and click the Copy Your PC's MAC Address button to enter the MAC

address.

Note: If you replace the Ethernet adapter in a computer that is using a DHCP

reservation, you will need to Copy the PC's MAC address again, because every

Ethernet adapter has a unique MAC address. The same goes for any network device.

If you replace a network device such as a print server, you will need to input the

MAC address of the new print server into the Static DHCP configuration.

2.2.5

DHCP Reservations list

Entries on this list can be enabled/disabled by toggling the Enable checkbox. Entries

can be modified by clicking on the paper and pencil icon. To delete an entry, click on

the trash can icon. After you’ve completed all modifications or deletions, you must

click the

Save Settings

button at the top of the page to save your changes. The

router must reboot before new settings will take effect. You will be prompted to

Reboot the Device

or

Continue

. If you need to make additional settings changes,

click

Continue

. If you are finished with your configuration settings, click the

Reboot

the Device

button.

2.2.6

Number of Dynamic DHCP Clients

In this section, you can see what LAN devices are currently leasing IP addresses. The

DHCP Client table displays the number of clients that are receiving an IP address

from the router. The computer name, MAC address, and IP address assigned to each

computer are displayed here as well.

Revoke:

Pressing

Revoke

cancels the lease of IP for a specific LAN device, freeing

this entry in the lease table. This feature is useful for freeing up addresses when the

client table is full or nearly full. Make sure you only revoke addresses from devices

that are no longer needed and/ or present on the network.

Reserve:

The

Reserve

option converts this dynamic IP allocation into a DHCP

Reservation and adds the corresponding entry to the DHCP Reservations List.

Wireless settings

The wizards cannot be used unless have set up a wireless network. Therefore we

start with Manual Wireless Network Setup
