Network configuration
This page allows you to
configure the various
aspects of the IP port and its
relationship with the local
network.
Gateway
This is the address of the device that links the local network (to which the iPEPS
is connected) to another network such as the Internet. Usually this is a network
switch or router and it will be used whenever a device to be contacted lies
outside the local network.
VNC port
This is the logical link through which communications with a remote VNC viewer
will be channelled (see What is a port?). The default setting is 5900 which is
a widely recognised port number for use by VNC software. However, in certain
circumstances it may be advantageous to alter this number - see Security issues
with ports for more details.
Note: The VNC port and HTTP port can be set to the same port number in order
to simplify router and firewall configuration. If this is done then the iPEPS will
“listen” for both types of traffic on the single port.
HTTP port
This is the logical link through which communications with a remote web
browser will be channelled. The default setting of 80 is an established standard
for web (HTTP – HyperText Transfer Protocol) traffic though this can be changed
to suit your local network requirements.
Clear IP access control
This option removes all entries from the IP access control feature within the
iPEPS. The IP access control feature (configurable by a remote admin user)
allows certain network address ranges to be denied access to the iPEPS. If set
incorrectly, it is possible to exclude all network users and so this option provides
an emergency recovery point.
MAC address
Media Access Control address – this is the unique and unchangeable code that
was hard coded within your iPEPS unit when it was built. It consists of six 2-digit
hexadecimal (base 16) numbers separated by colons. A section of the MAC
address identifies Adder Technology as the manufacturer, while the remainder is
effectively the unique electronic serial number of your particular unit.
Use DHCP
DHCP is an acronym for ‘Dynamic Host Configuration Protocol’. Its function is
particularly useful when connecting to medium size or larger networks. When
this option is selected, your iPEPS will attempt to locate a DHCP server on the
network. If such a server is located, it will supply three things to the iPEPS: an
IP address, an IP network mask (also known as a Subnet mask) and a Gateway
address. These are not usually granted permanently, but on a ‘lease’ basis for
a fixed amount of time or for as long as the iPEPS remains connected and
switched on. Discover allocations.
IP address
This is the identity of the iPEPS within a network. The IP address can be thought
of as the telephone number of the iPEPS. Unlike the MAC address, the IP
address can be altered to suit the network to which it is connected. It can either
be entered manually or configured automatically using the DHCP option. When
the DHCP option is enabled, this entry is greyed out.
Net mask
Also often called the ‘subnet-mask’, this value is used alongside the IP address
to help define a smaller collection (or subnet) of devices on a network. In this
way a distinction is made between locally connected devices and ones that are
reachable elsewhere, such as on the wider Internet. This process helps to reduce
overall traffic on the network and hence speed up connections in general.
