Description
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 system 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
system. 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 system you can specify the
range of boardroom IP addresses rather than needing to type in each
individual address. The allow list looks as follows:
Allow: 192.168.1.200-192.168.1.250
Note that we could have specified two of the IP addresses in the previous
example as a range.
Allow list with a range of IP
addresses and one or more
Putting the first two examples together, we want to permit access to IP
addresses in the range of boardroom computers (192.168.1.200-
