Set Up a Default DMZ Server

The default DMZ server feature is helpful when you are using some online games and

videoconferencing applications that are incompatible with Network Address Translation

(NAT). The router is programmed to recognize some of these applications and to work

correctly with them, but other applications might not function well. In some cases, one local

computer can run the application correctly if the IP address for that computer is entered as

the default DMZ server.

WARNING:

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 computer can be used to attack other computers on your

network.

The router usually detects and discards incoming traffic from the Internet that is not a

response to one of your local computers or a service that you configured in the Port

Forwarding/Port Triggering screen. Instead of discarding this traffic, you can specify that the

router forwards the traffic to one computer on your network. This computer is called the

default DMZ server.



To set up a default DMZ server:

1.

Launch a web browser from a computer or wireless device that is connected to the

network.

2.

In the address field of the web browser, enter

www.routerlogin.net

or

www.routerlogin.com

.

A login screen displays.

Launch a web browser from a computer or wireless device that is connected to the

network.

Change the LAN TCP/IP Settings

The router is 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 as follows:

•

LAN IP address

. 192.168.1.1

•

Subnet mask

. 255.255.255.0

These addresses are part of the designated private address range for use in private networks

and are suitable for most applications. If your network requires a different IP addressing

scheme, you can change these settings.

You might want to change these settings if you need a specific IP subnet that one or more

devices on the network use or if you have competing subnets with the same IP scheme.



To change the LAN TCP/IP settings:

1.

Launch a web browser from a computer or wireless device that is connected to the

network.

2.

In the address field of the web browser, enter

www.routerlogin.net

or

www.routerlogin.com

.

A login screen displays.

In the

IP Subnet Mask

field, type the subnet mask of the router.

The IP address and subnet mask identify which addresses are local to a specific device

and which must be reached through a gateway or router.

If you changed the LAN IP address of the router, you are disconnected when this change

takes effect.

To reconnect, close your browser, relaunch it, and log in to the router.

Specify the IP Addresses That the Router Assigns

By default, the router acts as a Dynamic Host Configuration Protocol (DHCP) server. The

router assigns IP, DNS server, and default gateway addresses to all computers connected to

the LAN. The assigned default gateway address is the LAN address of the router.

These addresses must be part of the same IP address subnet as the router’s LAN IP

address. Using the default addressing scheme, define a range between 192.168.0.2 and

192.168.0.254, although you can save part of the range for devices with fixed addresses.

The router delivers the following parameters to any LAN device that requests DHCP:

•

An IP address from the range that you define

•

Subnet mask

•

Gateway IP address (the router’s LAN IP address)

•

DNS server IP address (the router’s LAN IP address)



To specify the pool of IP addresses that the router assigns:

1.

Launch a web browser from a computer or wireless device that is connected to the

network.

2.

In the address field of the web browser, enter

www.routerlogin.net

or

www.routerlogin.com

.

A login screen displays.

3.

Enter the router user name and password.

The user name is

. The default password is

Specify the range of IP addresses that the router assigns:

a.

In the

Starting IP Address

field, type the lowest number in the range.

This IP address must be in the same subnet as the router.

b.

In the

Ending IP Address

field, type the number at the end of the range of IP

addresses.

This IP address must be in the same subnet as the router.

Reserve LAN IP Addresses

When you specify a reserved IP address for a computer on the LAN, that computer always

receives the same IP address each time it accesses the router’s DHCP server. Assign

reserved IP addresses to computers or servers that require permanent IP settings.



To reserve an IP address:

1.

Launch a web browser from a computer or wireless device that is connected to the

network.

2.

In the address field of the web browser, enter

www.routerlogin.net

or

www.routerlogin.com

.

A login screen displays.

3.

Enter the router user name and password.

The user name is

admin

. The default password is

password

. The user name and

password are case-sensitive.
