from connecting to the DSLAM or passing customer data. This may be identified at
various times such after power on or during operation through the use of self testing
or in operations which result in a unit state that is not expected or should not occur.
2 IP connected (the device has a WAN IP address from IPCP or DHCP and DSL is up
or a static IP address is configured, PPP negotiation has successfully complete – if
used – and DSL is up ) and no traffic detected. If the IP or PPPoE session is dropped
for any other reason, the light is turned off. The light will turn red when it attempts
to reconnect and DHCP or PPPoE fails.

Chapter 3 Web User Interface
This section describes how to access the device via the web user interface (WUI)
using an Internet browser such as Internet Explorer (version 5.0 and later).
3.1 Default Settings
The factory default settings of this device are summarized below.
• LAN IP address: 192.168.1.1
• LAN subnet mask: 255.255.255.0
• Administrative access (username: root , password: 12345 )
• WIFI access: enabled
Technical Note
During power on, the device initializes all settings to default values. It will then
read the configuration profile from the permanent storage section of flash memory.
The default attributes are overwritten when identical attributes with different values
are configured. The configuration profile in permanent storage can be created via
the web user interface or telnet user interface, or other management protocols.
The factory default configuration can be restored either by pushing the reset button
for more than five seconds until the power indicates LED blinking or by clicking the
Restore Default Configuration option in the Restore Settings screen.
3.2 IP Configuration
DHCP MODE
When the AR-5381u-NA2 powers up, the onboard DHCP server will switch on.
Basically, the DHCP server issues and reserves IP addresses for LAN devices, such
as your PC.
To obtain an IP address from the DCHP server, follow the steps provided below.
NOTE: The following procedure assumes you are running Windows XP.
However, the general steps involved are similar for most operating
systems (OS). Check your OS support documentation for further details.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Select Obtain an IP address automatically as shown below.
![](/img.php?id=2010249&img=bgf.png)

STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead.
![](/img.php?id=2010249&img=bg10.png)
15
STATIC IP MODE
In static IP mode, you assign IP settings to your PC manually.
Follow these steps to configure your PC IP address to use subnet 192.168.1.x.
NOTE: The following procedure assumes you are running Windows XP.
However, the general steps involved are similar for most operating
systems (OS). Check your OS support documentation for further details.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Change the IP address to the 192.168.1.x (1<x<255) subnet with subnet
mask of 255.255.255.0. The screen should now display as shown below.
STEP 4: Click OK to submit these settings.
![](/img.php?id=2010249&img=bg11.png)

5.13 DNS Proxy/Relay
DNS proxy receives DNS queries and forwards DNS queries to the Internet. After the
CPE gets answers from the DNS server, it replies to the LAN clients. Configure DNS
proxy with the default setting, when the PC gets an IP via DHCP, the domain name,
Home, will be added to PC’s DNS Suffix Search List, and the PC can access route with
“Comtrend.Home”.
DNS Relay
When DNS Relay is enabled, the router will play a role as DNS server that send
request to ISP DNS server and cache the information for later access. When DNS
relay is disabled, the computer will pull information from ISP DNS server.

5.17 Interface Grouping
Interface Grouping supports multiple ports to PVC and bridging groups. Each group
performs as an independent network. To use this feature, you must create mapping
groups with appropriate LAN and WAN interfaces using the Add button.
The Remove button removes mapping groups, returning the ungrouped interfaces
to the Default group. Only the default group has an IP interface.
To add an Interface Group, click the Add button. The following screen will appear.
It lists the available and grouped interfaces. Follow the instructions shown
onscreen.

Automatically Add Clients With Following DHCP Vendor IDs:
Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID
(option 60). The local DHCP server will decline and send the requests to a remote
DHCP server by mapping the appropriate LAN interface. This will be turned on when
Interface Grouping is enabled.
95
For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/VCI=0/33 is
for PPPoE while the other PVCs are for IP set-top box (video). The LAN interfaces are
ENET1, ENET2, ENET3, and ENET4.
The Interface Grouping configuration will be:
1. Default: ENET1, ENET2, ENET3, and ENET4.
2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor ID is "Video".
If the onboard DHCP server is running on "Default" and the remote DHCP server is
running on PVC 0/36 (i.e. for set-top box use only). LAN side clients can get IP
addresses from the CPE's DHCP server and access the Internet via PPPoE (0/33).
If a set-top box is connected to ENET1 and sends a DHCP request with vendor ID
"Video", the local DHCP server will forward this request to the remote DHCP server.
The Interface Grouping configuration will automatically change to the following:
1. Default: ENET2, ENET3, and ENET4
2. Video: nas_0_36, nas_0_37, nas_0_38, and ENET1.
