A management server from the Internet sees a managed LAN device as a combination of the access
Router's WAN IP address and a Virtual Port reserved for this device. When a TCP or UDP-based
management request (specified by the Protocol field) is received by the access Router from the Inter-
net, the IWE3200-H translates the destination IP address and destination port of the request to the
corresponding Device IP Address and Device Port. In other words, this request is passed through the
built-in NAT server of the Router and routed to the corresponding managed LAN device.
For example, Fig. illustrates a LAN device management scenario based on the settings values in
Fig. . AP1 can be managed from the management server by using a Web browser and a URL
"http://61.16.31.110:60001". AP2 can be managed by using a Web browser and a URL
"http://61.16.31.110:60002". AP3 can be managed from the management server by using an SNMP
manager program via IP address 61.16.31.110 and port 60003. Destination IP addresses and destina-
tion ports of management packets for AP1, AP2, and AP3 are translated to 192.168.168.201:80,
192.168.168.202:80, and 192.168.168.201:161, respectively. (161 is a well known port for SNMP
management.)
To specify a LAN device to manage:
1.
Give a name for this device in the Device Name text box.
2.
Type the Virtual Port, Device IP Address, Device Port, and Device MAC Address for this
device.
3.
Choose the type of the management protocol (TCP or UDP) from the Protocol drop-down list.
4.
Choose whether the Router communicates with the device wirelessly by WDS (Wireless) or by
Ethernet (Wired) from the Interface drop-down list.
5.
Select the corresponding check box next to the Device Name text box.
A valid input for the Virtual Port field must be between 60001 and 60100 inclusive.
NOTE:
The IP address in a Device IP Address text box and the Router's LAN IP address must
NOTE:
be in the same IP subnet.
The Device Name, Device MAC Address, and the Interface fields are informational.
NOTE:
They do not affect the inner workings of LAN device management.
