Note:

If you include port 80 on this section, you must set the port for remote

(web-based) management to a different number than 80, such as 8080, otherwise

the virtual server feature may not take effect.

4.2 DMZ Host

The DMZ (De-Militarized Zone) function disables the firewall on the router for

one device for a special purpose service such as Internet gaming or video

conferencing. Enabling DMZ host may expose your local network to potential

attacks. So it is advisable to use it with caution.

DMZ Host IP Address:

The IP Address of the device for which the router’s

firewall will be disabled. Be sure to statically set the IP Address of that device

for this function to be consistent.

Enable:

Check/uncheck to enable/disable the DMZ host feature.

OK:

Click to enable your settings.

Note:

Once enabled, the DMZ host loses protection from device's firewall and

becomes vulnerable to attacks.

4.3 DDNS

Dynamic DNS or DDNS is a term used for the updating in real time of Internet

Domain Name System (DNS) name servers. Dynamic DNS or DDNS is a term

used for the updating in real time of Internet Domain Name System (DNS) name

servers. We use a numeric IP address allocated by Internet Service Provider (ISP)

to connect to Internet; the address may either be stable ("static"), or may change

from one session on the Internet to the next ("dynamic"). However, a numeric

address is inconvenient to remember; an address which changes unpredictably

makes connection impossible. The DDNS provider allocates a static host name

to the user; whenever the user is allocated a new IP address this is

communicated to the DDNS provider by software running on a computer or

network device at that address; the provider distributes the association between

the host name and the address to the Internet's DNS servers so that they may

resolve DNS queries. Thus, uninterrupted access to devices and services whose

numeric IP address may change is maintained. (You need to have an account

with one of the Service Providers in the drop-down menu first.)

DDNS Service:

Select to enable/disable the DDNS feature.

Service Provider:

Select your DDNS service provider from the drop-down

menu. (Here you can see a list of available service providers. Note that service

providers not listed here are not available for use.)

User Name:

Enter the registered user name.

Password:

Enter the registered password.

Domain Name:

Enter the domain name you register, say, tenda.dyndns.org.

OK:

Click to activate your settings.

Note:

This feature is usually used together with virtual server and is disabled by

default. Configure necessary settings on port forwarding interface and enter the

information provided by your DDNS service provider on the DDNS screen.

Others can access your web server by simply entering http://tenda.dyndns.org in

their browser address bar.

4.4 UPNP

The Universal Plug and Play (UPnP) feature allows network devices, such as

computers from Internet, to access resources on local host or devices as needed.

UPnP-enabled devices can be discovered automatically by the UPnP service

application on the LAN. This feature is enabled by default. No settings are

required.

Enable UPnP:

Check/uncheck to enable/disable the UPnP feature.

OK:

Click to complete your settings.

4.5 Static Routing

When there are several routers in the network, you may want to set up static

routing. Static routing determines the path of the data in your network. You can

use this feature to allow users on different IP domains to access the Internet via

this device. It is not recommended to use this setting unless you are familiar with

static routing. In most cases, dynamic routing is recommended, because this

feature allows the router to detect the physical changes of the network layout

automatically. If you want to use static routing, make sure the rou

ter’s DHCP

function is disabled.

1.

Destination Network IP Address

: Specify a single IP address, say,

172.17.0.100, or an IP net segment, .say, 192.168.88.0.

2.

Subnet Mask

: Specify a Subnet Mask that corresponds to the specified

destination IP.

3.

Gateway

: Specify the IP address for next hop.

4.

OK:

Click to activate your settings.

Note:

1.

Gateway must be on the same IP net segment as device's LAN/WAN IP

address.

2.

Subnet Mask must be entered 255.255.255.255 if destination IP address is a

host.

3.

Subnet Mask must be entered accordingly if destination IP address

represents an IP network segment. It must correspond to the specified IP

address. For example, for IP address of 10.0.0.0, you may enter a subnet

mask of 255.0.0.0.

4.6 Routing Table

This page displays the device core routing table which lists destination IP, subnet

mask, gateway, hop count and interface.

The principal task for a router is to look for an optimal transfer path for each

data packet passing through it, and transfer it to the specified destination. To

complete this work, the router stores and maintains related data of various

transfer paths, i.e. establishing a routing table, for future route selection.

URL Filter

To better control LAN PCs, you can use the URL filter functionality to allow or

disallow such PCs to access certain websites within a specified time range.
