Pearl Mini User Guide Restrict viewers by IP address
Example Description
Your list can have multiple ranges and multiple distinct IP addresses, provided
they are separated by commas.
Allow list with a range of
IP addresses, distinct
IP addresses, and an
exception
Building on the previous examples, consider a situation where you want the
CEO’s computers (192.168.1.50, 192.168.1.51, 192.168.75) and all boardroom
computers (192.168.1.200-192.168.1.250) to access the broadcast, with the
exception of the public boardroom computer (192.168.1.211). Use both allow
and deny lists to create the rule as follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51,
192.168.1.75
Deny: 192.168.1.211
Both lists can have multiple ranges and multiple distinct IP addresses, provided
they are separated by commas.
The following table lists some sample deny lists.
Table 52 Example deny lists
Example Description
Deny list with distinct IP
addresses
Another simple allow/deny list is to use the list of known IP addresses to list
specific denied IP addresses. All other addresses are allowed access to the
broadcast.
For example imagine your system is accessible on your local area network
(LAN) and you want to allow any computer on the LAN can access the stream
except your publicly-accessible boardroom (with IP address 192.168.1.211).
You can use the following deny list (leave the allow list empty) to permit all
computers except the boardroom computer:
Deny: 192.168.1.211
As with allow lists, your deny list can specify a range of IP addresses, and can
specify multiple ranges or distinct IP addresses in a comma-separated list.
Deny list with a range of IP
addresses
Consider a situation where you want every computer on the network to access
the broadcast, with the exception of the CEO’s desktop, laptop and tablet
computers. Additionally, boardroom computers should not be permitted with
the exception of the cafeteria computer (IP address 192.168.1.222).
The deny list is an "exception" list for the allow list. So to craft the rule described
above we need to allow all the computers in the local subnet, then deny specific
sub-ranges including two groups of boardroom computers ensuring the
cafeteria computer's IP address is not in the deny list:
