DVI Broadcaster DL User Guide
If any addresses are specified in the
Deny IP’s
field, access to the broadcast will be
forbidden for these addresses and allowed for all other addresses.
The list of denied IP addresses has a higher priority over the list of allowed IP
addresses. An example of how this is implemented would be the following:
1.
In the
Deny IP’s
field enter
172.20.1.20-172.20.1.30
.
2.
In the
Allow IP’s
field enter
172.20.1.22, 172.20.1.33
.
Access to the broadcast will be forbidden for the entire subset of addresses -
172.20.1.20-30
.
The set of users must have a fixed IP address or a range of IP addresses through
which they connect to the internet. Individual computers may have dynamic server-
assigned addresses but as long as they use a gateway with a static address to access
the internet, this feature can be configured
IP authentication is primarily about convenience, rather than extra security. The
level of security is comparable with that of a password-based authentication. Bear in
mind that anyone who has access to a computer within the specified range will be
able to access the broadcast without having to provide log in credentials. Also it is
probably not possible to restrict access to a single computer since in most networks
a number of computers share a single gateway to the internet.
The table below shows the fields used in configuring IP-based authentication for
viewers.
Deny IP’s
Enter individual IP addresses separated by a comma or a range of IP
addresses that are denied access to the broadcast. To specify a range
of addresses, use a hyphen (-).
Example 1:
172.20.1.20, 172.20.1.32
Example 2:
172.20.1.1-100
Allow IP’s
Enter individual IP addresses separated by a comma or a subset of IP
addresses that are granted access to the broadcast. To specify a range
of addresses, use a hyphen (-).
11.4.3
Delete the Viewer Password
The viewer password can be deleted if viewers are not required to enter a password
to access the broadcast.
