3.8.7 DMZ
---End
Enter Protocol name://WAN port IP address:External port in the address bar of a web browser
on a computer over the internet to access the resources on the LAN server. In this example,
enter http://102.33.66.88:80.
Note
If you are uncertain about the WAN IP address of the router, you can use both the virtual server and
DDNS functions to allow internet users to access the LAN server using a domain name.
A DMZ host on a LAN can communicate with the internet without limit. You can set a
computer that require higher internet connection throughput, such as a computer used for
video conferencing or online gaming, as a DMZ host for better user experience.
- 82 -
Note
A DMZ host is not protected by the firewall of the router. A hacker may leverage the DMZ host to
attack your LAN. Therefore, enable the DMZ function only when necessary.
Manually set the IP address of the LAN computer that functions as a DMZ host, to prevent IP address
changes, which lead to DMZ function failures.
Security software, antivirus software, and the built-in OS firewall of the computer may cause DMZ
function failures. Disable them when using the DMZ function. If the DMZ function is not required, it
is recommended that you disable it and enable your firewall, security, and antivirus software.
To configure the DMZ function, perform the following procedure:
Step 1 Choose Advanced Settings > DMZ.
Step 2 Set DMZ to the state.
Step 3 Set DMZ Host IP to the IP address of the DMZ host.
Step 4 Click Save.

218.88.93.33
Application Scenario
An AC18 is used to set up a LAN at an apartment and the router must be logged in and
managed over the internet. Assume the public IP address of the router is 102.33.66.88 and
the public IP address of the computer for remotely login is 218.88.93.33.
The following figure shows the application scenario.
WAN IP address of the router:
102.33.66.88
Configuration
IP address of computer 2:
Note
The computer used to remotely log in to the router web UI must be assigned a public IP address. If it is
assigned a private IP address, use the public IP address of the router to which the computer connects for
remote login. Private IP addresses are not applicable to remote management.
Step 1 Choose Advanced Settings > Remote Management.
- 84 -
Step 2 Set Remote Management to the state.
Step 3 Set Remote IP Address to the WAN IP address (public IP address) of the computer where
remote management is to be performed. In this example, set it to the WAN IP address of
computer 2, which is 218.88.93.33. If you are uncertain about the IP address of the computer,
set this parameter to 0.0.0.0 (default value). In this case, all computers can log in to the
router web UI over the internet.
Step 4 Set Port to the port number of the web service, which is generally 8080. You can also select a
port number from the 1024~65535 range but the port number must not be the same as that
of the virtual server.
Step 5 Click Save.
Remote Access
3.8.9 IPTV
---End
Enter http://102.33.66.88:8080 in the address bar of computer 2 and log in to the router web
UI to perform remote management.
Note
The public IP address of the router may change. Therefore, you need to confirm the IP address each time
you want to remotely log in to the router web UI, which is troublesome. To address this issue, you can
use the DDNS function to bind the public IP address with a fixed domain name, so that you can use the
domain name to log in to the router web UI. To implement this measure, configure the DDNS function
and then the remote management function of the router.
This router supports the multicast and STB functions. To configure the functions, choose
Advanced Settings > IPTV. By default, the functions are disabled.
- 85 -
Multicast
This function enables you to access multicast resources over the internet. If you want to watch
live videos, it is recommended that you enable this function.
Step 1 Set Multicast to the state.
STB
Step 2 Click Save.
---End
If you connect an STB to the router and subscribe to an IPTV service, enable the STB function.
- 86 -
Step 1 Set Set-top Box to the state.
Step 2 Set Select a zone to the VLAN of your IPTV service. If the service has no VLAN ID, select No
VLAN ID. Otherwise, select Custom and enter the VLAN ID of the service. Shanghai indicates
the IPTV service VLAN in Shanghai.
Step 3 Click Save.
Step 4 Connect the STB to the 4/IPTV port of the router. The connected port functions only as an
IPTV port.
---End
You can then watch IPTV programs on a smart TV connected to your router.
3.8.10 Firewall
The firewall is used to protect the router against some attacks, helping ensure network
security. By default, the firewall of the router is enabled. It is recommended that you retain
the default setting.
Note
After configuring the router, you may need to configure your STB as well. For details, refer to the user
guide for your STB or TV.

3.8.11 Static Routing
Routing is performed to select the best route for delivering data from a source address to a
destination address. A static route is a manually configured route, which is simple, efficient,
and reliable. Appropriate static routes help reduce the number of route selection problems
and reduce route selection load, increasing the packet forwarding speed.
To configure static routes, choose Advanced Settings > Static Routing.
The following table describes the parameters.
- 88 -
Parameter
Description
Target
Network
It specifies the IP address of a packet destination.
Subnet Mask
It specifies the subnet mask of the IP address of a packet destination.
Gateway
It specifies the IP address of the next hop of packets transmitted from
the router.

Verify that you can access the router web UI at 192.168.5.1 or tendawifi.com.
After the settings take effect, the system displays the login page at the new LAN IP address.
After you log in to the router web UI, the system displays the updated LAN IP address IP
address range of the router on the LAN IP Settings page. See the following figure. The LAN IP
address is changed to 192.168.5.1 and the IP address range is changed to 192.168.5.100~200.
That is, the router assigns only the IP addresses within this range to devices connected to the
router.
- 92 -
Setting DNS Server Addresses
This function enables you to set DNS server addresses for devices connected to the router. If
you do not configure DNS settings, the DHCP server of the router assigns the default DNS
server address (LAN IP address of the router) to the devices.
- 93 -
Parameter
Description
LAN IP Address
It specifies the LAN IP address of the router, that is, the login
address of the router web UI.
DHCP Server
(default): It indicates that the server that assigns one IP
address within a specified IP address range to each device
connected to the router.
: It indicates that no IP address is assigned to the devices
connected to the router (such as laptops and mobile phones).
These devices can access the internet only after IP addresses are
manually set on them. Manual IP address setting is complicated
and may easily cause IP conflicts. Generally, it is recommended
that you enabled the DHCP server.
IP Address Range
It specifies the range of IP addresses that can be assigned to devices
connected to the router.
Lease Time
It specifies the validity period of one IP address assigned to a device
connected to the router.
DNS Settings
It specifies the primary and secondary DNS servers of devices
Enabling or Disabling the DHCP Service
The default setting is recommended. If you need to change the settings, refer to the
parameter description in the following table.
Note
By default, the DHCP server of the router is enabled. It is recommended that you retain the default
settings. If you disable the DHCP server, you need to set IP address information on each device
connected to the router, which will probably cause IP address conflicts.
It is recommended that you retain the default DHCP server settings to ensure internet connectivity.
The following table describes the parameters.
