4.4.2.1 IP Configuration (continued)
Gateway Address – This points to the router that forwards traffic to a destination
address outside of the subnet on which the iServer resides. This is the IP address of the
router which functions as a gateway. When DHCP is enabled this field will be dimmed.
The iServer's default Gateway address is 0.0.0.0. Consult with your IT department for
obtaining a gateway address.
DNS Address – In order to use the hostname to access the iServer, the DNS server on
your network must be configured, refer to Section 3.4. iServer plays the role of a DNS
client, in the sense that the iServer will actively query the DNS server for the IP address
associated with a particular domain name. When DHCP is enabled this field will be
dimmed. The iServer's default DNS address is 0.0.0.0. Consult with your IT department
for obtaining a DNS address.
Host Name – If DHCP is enabled, the iServer will send this name to the DHCP server.
This name is used so that the iServer can be accessed based on a specific name instead
of an IP address. For example, instead of using http://192.168.1.200
address), you would use http://ithxA838 or any name up to sixteen (16) alphanumeric
characters. The default Host Name for an iServer is "ithx" followed by the last four digits
of the MAC address of that particular iServer.
On Windows servers where DHCP and DNS are separate functions it's very
important to configure the DHCP server to communicate with DNS in order for
the iServer's Host Name to correctly respond. If you cannot access the iServer
using its Host Name, please contact your network administrator to make sure
DHCP and DNS servers are linked together.
Protocol – It's the network protocol the iServer communicates with the Ethernet
Network. Options are TCP and UDP. The default is TCP.
Local Port – The default port is 2000. Refer to Section 3.6.
Web Server Port – The default port is 80. This is the primary port number for the HTTP
protocol used for communication between internet browsers and web sites/web servers.
Web servers open this port then listen for incoming connections from web browsers.
Similarly, when a web browser is given an IP address (like the iServer's IP address),
it assumes that the iServer's web server is listening for connections on port 80. If this
port is changed to anything but 80 then on the browser the new port number must be
indicated with a colon (
changed to 500, you will then need to type http://192.168.1.200:500 on the browser to
access the iServer's web server.
One of the applications where the Web Server Port number may need to change
is when users want to access the iServer's web server from outside the local
area network (i.e. Internet). By setting up "Port Forwarding" inside a router that
is the gateway to that local area network this task can be accomplished. "Port
Forwarding" technique uses the Web Server Port number to forward the Internet
connection to the iServer on the LAN.
Web Link Title – This is a text field that appears on the button on the iServer's Web Link
Page, refer to Section 4.7. This can describe the Web Link Address assigned below.
Web Link Address – This provides a link to any TCP/IP node on the network or any
Web link on the Internet. Examples would be www.123abc.com or if you have a device
with an embedded Web server (just like the iServer) once you enter its IP address in this
field and click on the Web Link button on the iServer's Welcome page you'll be able to
access your device using the same browser interface.
