Table 14 IP Based Restriction Fields
Label Description/Options
Allow IP's Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are permitted to view broadcasts from the
device, provided their IP address is not in the Deny IP’s list.
To allow all (except IP addresses in the deny list, if any), leave the field blank.
You can use the Allow list by itself, or in conjunction with the Deny IP’s list as an exception
to a rule in the allow list.
Deny IP's Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are not allowed to view broadcasts from the
device, unless their IP address is in the Allow IP’s list. If a specific IP address is in both lists,
access to the stream is denied.
You can use the Deny list by itself, or in conjunction with the Allow IP’s list as an exception
to a rule in the allow list.
Examples
Allow List with Distinct IP Addresses
The simplest allow/deny list is to use the list of known IP addresses to craft a list of allowed IP addresses. All
other addresses are denied access to the broadcast.
For example if your device is accessible on your local area network (LAN) and you want to make sure only the
CEO’s specific desktop, laptop and tablet computers (with IP Addresses 192.168.1.50, 192.168.1.51, and
192.165.1.75, respectively) can connect to the broadcast, construct the following allow list:
Allow: 192.168.1.50, 192.168.1.51, 192.168.1.75
Allow List with a Range of IP Addresses
Sometimes you’ll want a range of computer IP addresses to connect to your device. This may happen when you
have one range of IP addresses assigned to desktop computers (i.e. in the range 192.168.1.1 to 192.168.1.100)
and another range assigned to boardroom computers (i.e. the range 192.168.1.200 to 192.168.1.250). If you
only want the boardroom computers to connect to broadcasts from the device you can specify the range of
boardroom IP addresses rather than needing to type in each individual address. The allow list looks as follows:
