forwarded to specific internal devices and computers. Each port
forwarding entry defines a source port and a target IP address.
Before adding or removing a port forwarding entry, save all changed
settings.
Any changes not saved will be lost when a port forwarding
entry is added or deleted.
2.3.6.2. Port Range Forwarding
Port range forwarding works similarly to port forwarding. Unlike port
forwarding, instead of a single port, a range of ports is forwarded to
the same range of ports at the internal target IP address.
2.3.6.3. Port Triggering
Port triggering is a kind of port range forwarding where outgoing
traffic on specific ports enables previously defined port forwards for
the activating device. This temporarily opens required ports when
specific applications are opened on computers on the LAN.
This offers
a greater level of security than port forwarding or port range
forwarding because the ports are only opened when needed.
2.3.6.4. UPnP
UPnP allows UPnP capable applications and devices to open and close
required ports automatically as needed. This is simple to use and does
not require further configuration steps.
2.3.6.5. DMZ
A DMZ computer is a special computer in the internal network that gets
all incoming traffic forwarded. The task of that computer is managing
this traffic. When the DMZ feature is activated the internal firewall
is activated. This can pose a security issue if not handled with care.
Furthermore, several services of the router, that have to be
accessible from the WAN side, will not work because the associated
traffic is forwarded to the DMZ computer.
2.3.6.6. QoS
QoS (Quality of Service) is a procedure to prioritise network traffic
by application. Specific services can be assigned specific bandwidth.
Aside from upstream and downstream bandwidth, you can define settings
for specific services and IP and MAC address ranges.
2.3.7.
Administration
2.3.7.1. Management
The Management section contains settings for remotely accessing the
router and other basic settings that are usually not changed. The
settings for the language used in the Web GUI are also located here.
You may choose between Chinese (simplified & traditional), Croatian,
Dutch, French, German, Hungarian, Italian, Japanese, Latvian, Polish,

Portuguese, Romanian, Russian, Slovenian, Spanish, and Swedish.
The
default setting is English.
Before using Telnet or SSH, activate the associated service(s) in this
section.
2.3.7.2. Keep Alive
Keep-Alive lets you configure monitoring options that automatically
reboot the router if a service malfunction causes it to fail to
respond.
2.3.7.3. Commands
Entering Linux commands is one of the most powerful ways to access the
router’s functionality. This enables you to access services and
configure options that are not accessible via the Web GUI. Using shell
commands can lead to unexpected results. Use them with utmost care.
Aside from executing the shell commands directly you can also save
custom start up and firewall scripts.
2.3.7.4. WOL
With Wake-on-LAN, you can send special data packets to compatible
devices on your LAN, causing them to exit sleep mode.
WOL data packets can be triggered manually or scheduled automatically.
2.3.7.5. Factory Defaults
With this feature you can reset the router’s settings to factory
defaults. After a reset, the router will restart.
2.3.7.6. Firmware Upgrade
The firmware upgrade option can be used to install a different
firmware version. When doing this you can choose if the router’s
settings will be restored to factory defaults or kept.
2.3.7.7. Backup
You can use this feature to store your current configuration into a
backup file, or to restore from a previously stored configuration.
This also makes it simple to set up a number of routers with the exact
same configuration.
2.3.8.
Status
2.3.8.1. Router
The status screen displays information about the router, such as cpu
load, memory consumption, and currently active IP connections. Status
is updated automatically.

Page 18 / 171
2.3.8.2. WAN
If the WAN interface is enabled, this screen displays WAN settings and
throughput statistics.
2.3.8.3. LAN
Here you can find LAN-related information like active clients and DHCP
clients.
2.3.8.4. Wireless
The wireless LAN status screen displays the current wireless LAN
interface configuration, wireless LAN clients (in AP modes), and
access points (in client modes). If there’s more than one wireless LAN
interface, you can switch between them via the interface pull down
menu.
2.3.8.5. Bandwidth
Bandwidth monitoring displays real time diagrams for incoming and
outgoing traffic for each network interface.
2.3.8.6. SysInfo
The SysInfo screen combines the most important information of the
other status pages. By default, the SysInfo page can be accessed from
LAN devices without authentication.
That can be changed in the
Management
section of the
Administration
area.

3. Use Cases
The following use cases relate to the most commonly used router
configurations. The related router configuration is explained step by
step.
3.1. Access Point
Access Point (AP, sometimes also called “Infrastructure Mode”) is the
mode where the router is also the central wireless hub that connects
to the LAN and provides access to wireless devices. These wireless
clients of the AP can communicate with each other and with wired
devices on the network such as the Internet.
Connect your computer to the router as described in 2.1. and access
the web interface according to 2.2.
3.1.1.
Access Point with NAT / DHCP
Setup -> Basic Setup
WAN Setup
o
In ”Connection Type”, choose the type of WAN connection you want
to use and complete the related settings.
Network Setup
o
Enter the desired LAN IP address for the router into “Router IP“.
o
Set “DHCP Type“ to “DHCP Server“ (this is the default).
o
“Enable“ DHCP Server (this is the default).
o
Adjust the DHCP address range to match your requirements.
Time Settings
o
Choose your time zone.
Click “Save“.
Wireless -> Basic Settings

Enter your country in “Regulatory Domain”
In the “Antenna Gain“ field, please enter the gain of the antenna on
your router. The firmware will adjust the transmit power accordingly
to meet regulatory requirements. Please keep in mind that very long
cables can dampen the HF signal thus reducing the usable antenna
gain.
Configure “Wireless Mode“ to “AP“
Set your desired wireless mode in “Wireless Network Mode“. Please
note that mixed modes will lead to reduced performance because of
maintaining compatibility.
Enter a name for your wireless network into “Wireless Network Name
(SSID)”
Click “Save“
Wireless -> Wireless Security
Choose and configure a security mode.
Please note that WEP is
insecure and should only be used if no other option is available.
Click “Apply Settings“
You can now connect the router to the Internet and your local network.
After you successfully connect wireless devices, they will then be
displayed on the “SysInfo” and “WLAN Status” pages.
3.1.1.
Access Point attached to a network / Internet gateway
Setup -> Basic Setup
WAN Setup
o
For “Connection Type“, choose “Disabled”.
Network Setup
o
Enter the desired LAN-side IP address for the router into “Router
IP“.
o
Set the “DHCP Type“ to “DHCP Server“ (this is the default).
o
“Disable” “DHCP Server“.
Time Settings
o
Choose your time zone.
Click “Save“.
Wireless -> Basic Settings
Enter your country in “Regulatory Domain”
In the “Antenna Gain“ field, please enter the gain of the antenna on
your router. The firmware will adjust the transmit power accordingly
to meet regulatory requirements. Please keep in mind that very long
cables can dampen the HF signal thus reducing the usable antenna
gain.
Configure “Wireless Mode“ to “AP“
Choose a wireless mode in “Wireless Network Mode“. Please note that
mixed modes will lead to reduced performance because of maintaining
compatibility.
