Incoming traffic from the Internet is normally discarded by the router unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports menu.
Instead of discarding this traffic, you can have it forwarded to one computer on your network. This
computer is called the Default DMZ Server.
The WAN Setup menu, shown below lets you configure a Default DMZ Server.
To assign a computer or server to be a Default DMZ server, follow these steps:
1.
Click
WAN Setup
on the Advanced section of the main menu.
2.
Type the IP address for that server. To remove the default DMZ server, replace the IP address
numbers with all zeros.
3.
Click
Apply
to save your settings.
•
Respond to Ping on Internet WAN Port
If you want the router to respond to a 'ping' from the Internet, click the ‘Respond to Ping on
Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it allows
your router to be discovered. Don't check this box unless you have a specific reason to do so.
•
Setting the MTU Size
The default MTU size is usually fine. The normal MTU (Maximum Transmit Unit) value for
most Ethernet networks is 1500 Bytes. For some ISPs, particularly some using PPPoE, you
may need to reduce the MTU. This should not be done unless you are sure it is necessary for
your ISP.
Any packets sent through the router that are larger than the configured MTU size will be
repackaged into smaller packets to meet the MTU requirement. To change the MTU size:
Under MTU Size, enter a new size between 64 and 1500. Then, click Apply to save the new
configuration.
Note:
DMZ servers pose a security risk. A computer designated as the default DMZ
server loses much of the protection of the firewall, and is exposed to exploits from the
Internet. If compromised, the DMZ server can be used to attack your network.

Using LAN IP Setup Options
The LAN IP Setup feature is under the Advanced heading of the main menu. This feature allows
configuration of LAN IP services such as DHCP and RIP. From the Main Menu of the browser
interface, under Advanced, click on LAN IP Setup to view the LAN IP Setup menu, shown below.
Figure 6-5:
LAN IP Setup Menu
The router is shipped preconfigured to use private IP addresses on the LAN side, and to act as a
DHCP server. The router’s default LAN IP configuration is:
•
LAN IP addresses—192.168.61.1
•
Subnet mask—255.255.255.0
These addresses are part of the IETF-designated private address range for use in private networks,
and should be suitable in most applications. If your network has a requirement to use a different IP
addressing scheme, you can make those changes in this menu.
The LAN IP parameters are:

•
IP Address
This is the LAN IP address of the router.
•
IP Subnet Mask
This is the LAN Subnet Mask of the router. Combined with the IP address, the IP Subnet Mask
allows a device to know which other addresses are local to it, and which must be reached
through a gateway or router.
•
RIP Direction
RIP (Router Information Protocol) allows a router to exchange routing information with other
routers. The RIP Direction selection controls how the router sends and receives RIP packets.
Both is the default.
—
When set to Both or Out Only, the router will broadcast its routing table periodically.
—
When set to Both or In Only, it will incorporate the RIP information that it receives.
—
When set to None, it will not send any RIP packets and will ignore any RIP packets
received.
•
RIP Version
This controls the format and the broadcasting method of the RIP packets that the router sends.
(It recognizes both formats when receiving.) By default, this is set for RIP-1.
—
RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you
have an unusual network setup.
—
RIP-2 carries more information. RIP-2B uses subnet broadcasting.
Using the Router as a DHCP server
By default, the router will function as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the router's LAN. The assigned default gateway address is the LAN address of the router. IP
addresses will be assigned to the attached computers from a pool of addresses specified in this
menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
Note:
If you change the LAN IP address of the router while connected through the
browser, you will be disconnected. You may need to restart your computer for the new IP
address setting to take effect.

For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See
“IP
Configuration by DHCP
” on
page B-10
for an explanation of DHCP and information about how to
assign IP addresses for your network.
If another device on your network will be the DHCP server, or if you will manually configure the
network settings of all of your computers, clear the ‘Use router as DHCP server’ check box.
Otherwise, leave it checked.
Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP
Address. These addresses should be part of the same IP address subnet as the router’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.61.1
and 192.168.61.253, although you may wish to save part of the range for devices with fixed
addresses.
The router will deliver the following parameters to any LAN device that requests DHCP:
•
An IP Address from the range you have defined
•
Subnet Mask
•
Gateway IP Address (the router’s LAN IP address)
•
Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu;
otherwise, the router’s LAN IP address)
•
Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu
Using Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer will always
receive the same IP address each time it access the router’s DHCP server. Reserved IP addresses
should be assigned to servers that require permanent IP settings.
To reserve an IP address:
1.
Click
Add
.
2.
In the IP Address box, type the IP address to assign to the computer or server.
(choose an IP address from the router’s LAN subnet, such as 192.168.61.X)
3.
Type the MAC Address of the computer or server.
(Tip: If the computer is already present on your network, you can copy its MAC address from
the Attached Devices menu and paste it here.)
4.
Click
Apply
to enter the reserved address into the table.

Note: The reserved address will not be assigned until the next time the computer contacts the
router's DHCP server. Reboot the computer or access its IP configuration and force a DHCP
release and renew.
To edit or delete a reserved address entry:
1.
Click the button next to the reserved address you want to edit or delete.
2.
Click Edit or Delete.
How to Configure Static Routes
Static Routes provide additional routing information to your router. Under normal circumstances,
the router has adequate routing information after it has been configured for Internet access, and
you do not need to configure additional static routes. You must configure static routes only for
unusual cases such as multiple routers or multiple IP subnets located on your network.
From the Main Menu of the browser interface, under Advanced, click on Static Routes to view the
Static Route menu, shown below.
