3.1 How to start out to configure router
Step1. Connect the MIS engineer’s PC and IGR-2500’s LAN port to the same Hub / Switch, and launch
the browser (IE or Netscape) to link the IGR-2500 appliance. The default IP address is
http: //192.168.1.1
Step2. Administrator will be requested for User Name and Password when entering IGR-2500 system.
(Figure 3-1)
User Name : airlive
Password : airlive
Click OK.
Figure 3-1 Login page

Step3. Configure each WAN port separately, and the other function you would like to use, such as Load
Balance, Bandwidth Management, or else. (Figure 3-2)
Figure 3-2 Configure WAN port setting
You can refer to the manual for more understanding of else router’s feature.

3.2 System Status
3.2.1 Link Status
You can get the following information in Link Status window: (Figure 3-3)
-LAN Status
-WAN Status
-DMZ Status
-Firmware Version
-DHCP Table
Figure 3-3 Link Status
10

11
LAN Status: Shows the information of MAC Address, IP Address, Subnet Mask and DHCP Status
(Enable/Disable).
WAN Status: Shows the information of MAC Address, IP Address, Subnet Mask and WAN Status on each
or all WAN ports.
DMZ Status: Shows the information of MAC Address, IP Address, and Subnet Mask.
Firmware version: version of software and its released date.
DHCP Table: Shows the information of MAC Address and IP Address.

3.2.2 Data Monitor
Differ with Link Status window, Data Monitor window provides detail packet transfer status. It includes 2 kinds
of real time data per each WAN port. (Figure 3-4)
Figure 3-4 Data Monitor
Current Session:
TCP Session:
UDP Session:
ICMP Session:

Usage (%): For example, WAN1 usage% = WAN1totalpackets %
(WAN1+WAN2)totalpackets
Byte Received
Byte Transmitted
Total Bytes: Total packets transfer by each WAN port
NAT Table: list current user detail NAT data. (Figure 3-5)
Refresh: update data monitor table to display newest data
12
Clear Counter: reset Data Counter data to 0, and restart to accumulate the packets.

Figure 3-5 NAT Table
The packets start to accumulate from:
1. Router powers on
2. Clear counter
3. Counter reaches upper the limitation (4294967K), and then the counter will reset to 0
automatically.
13

3.3 WAN Configure
There are several WAN function can be made in this display, you can configure functions to each WAN port
separately.
Connect to:
Internet: WAN port is connected to Internet through ADSL/Cable modem
Intranet: WAN port is connected to another router LAN port, work together with “Static Route”
function, can restrict specific IP packet to a dedicate route path.
Healthy Check:
Enable: Enable the feature to check whether the WAN link is alive or not. System provides 3
methods to check the WAN link, Ping IP, DNS, and Time Server; you can choose it
with each method or both. It is suggested to select at least 2 methods to check the
WAN link, in order to avoid router making wrong action due to Internet Server
disable. (Figure 3-6)
Disable: If “Time Server” does not exist, this function will disable automatically.
Figure 3-6 Healthy Check
Dynamic IP: Connect to Cable Modem and obtain an IP address from ISP automatically.
PPPoE: Connect to Dial Up DSL
Static IP: Connect to Leased DSL
Schedule: This function allows you to control each WAN port link up/down time by daily/weekly.
Start Time: (hh:mm)
End Time: (hh:mm)
Weekly: choose by day
When you enable Schedule function, the WAN connection will follow the Schedule to link up or down,
no matter DOD (Dial-on-demand) function is enabled or disabled.
14

WAN Link Mode: You can choose the WAN interface type in order to follow the connecting type of ISP.
Auto Sense
10Mbps Half Duplex
10Mbps Full Duplex
100Mbps Half Duplex
100Mbps Full Duplex
3.3.1 WAN Type – Dynamic IP
Usually it's used to connect CABLE modem. You won't need to assign IP address, and the IGR-2500 will get
the IP address from ISP automatically. (Figure 3-7)
When you choose Dynamic IP, you only need to save this selection, and reboot router when you finish
configuring all parameter.
Figure 3-7 Dynamic IP
15

3.3.2 WAN Type – PPPoE
Connect to ISP via dial-up connecting, ISP will assign a legal IP to you after the user Id and password had
been passed. (The user Id and password here are provided by your ISP.) (Figure 3-8)
Figure 3-8 PPPoE
Account: The user name provided by ISP, the character can be entered up to 60.
Password: The password provided by ISP, the character can be entered up to 60.
Service Name: This is optional. The Service name is needed if ISP requires for it.
Max. Idle Time (min): The default value is 0, means not to check the idle time, so the connection will
remain connecting unless user disconnects it by manually.
Dial On Demand: Auto connect function
Manual: You need to initiate WAN connection manually, by clicking WAN1 connect or WAN2
connect button in System Status ÆLink Status menu. However, power up or
reset also can initiate the WAN connection.
Dial-on-demand: Whenever a user is trying to access the Internet from his computer, this
WAN port will start connection automatically if it is disconnected.
Always-on: The WAN port will try to establish the connection as long as it is disconnected,
no matter this port is used or not.
16

About “Always-on” function, normally you need to combine "Healthy Check" function together, then
"Always-on" can work more perfectly because there is an ADSL modem between router & ISP equipment. In
physical layer, if ADSL line fails but ADSL modem is still alive, and router can not detect the line status unless
ISP sends a disconnected packet to router. So if ADSL line is in abnormal up-down, sometimes router can not
get disconnect packet from ISP. Maybe in ISP side, it treats line as disconnected status, but router seems like
to be still in "connecting" status.
If you enable "Healthy Check" in each line, then router can automatically send packet out through WAN to
detect whether line is active or not. (1 packet per 30 sec) This function will be helpful to judge the line status,
and provide correct information to router for the Link Status.
It's better to enable at least 2 options in "Healthy Check", in order to avoid misjudgments when only 1
option is selected and the option server fails to respond the request.
3.3.3 WAN Type – Static IP
When user applied the leased line from ISP, the service provider will offer user the real IP, Subnet Mask,
Gateway and DNS. You need to indicate the static IP manually. (Figure 3-9)
Figure 3-9 Static IP
