Network configuration
This page allows you to configure the various aspects of the IP port.
MAC address
Media Access Control address – this is the unique and unchangeable code that was
hard coded within your ALIF 2112T 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 the manufacturer, while the remainder is effectively the unique electronic serial
number of your particular unit.
IP Address
This is the identity of the ALIF 2112T within a network. The IP address can be thought of
as the telephone number of the ALIF 2112T. 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 grayed out.
IP Network 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.
IP Gateway
This is the address of the device that links the local network (to which the ALIF 2112T
is connected) to another network such as the wider Internet. Usually the actual gateway
is a network router and it will be used whenever a required address lies outside the
current network.
VNC Port
This is the logical link through which communications with a remote VNC viewer will be
channelled. The default setting is 5900 which is a widely recognized 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.
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.
IP Access Control
This section allows you to optionally specify ranges of addresses which will or won’t
be granted access to the ALIF 2112T. If this option is left unchanged, then the default
entry of ‘+0.0.0.0/0.0.0.0’ ensures that access from all IP addresses will be permitted. See
Setting IP access control
for details.
