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
(IP
address), you would use
http://isdb870
or any name up to sixteen (16) alphanumeric
characters. The default Host Name for an iServer is "
isd
" followed by the
last four digits
of the MAC address of that particular iServer.
On Windows servers where the DHCP and DNS are separate functions it’s very
important to configure the DHCP server to communicate with the 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 the 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 (
:
) after the IP address. For example, if the Web Server Port is
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.
