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
system, 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
system, 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.

other addresses are denied access to the broadcast.
