Accessible IP
The PT-7728 uses an IP address-based filtering method to control access.
You may add or remove IP addresses to limit access to the PT-7728. When the accessible IP list is
enabled, only addresses on the list will be allowed access to the PT-7728. Each IP address and
netmask entry can be tailored for different situations:
y
Grant access to one host with a specific IP address
For example, enter IP address 192.168.1.1 with netmask 255.255.255.255 to allow access to
192.168.1.1 only.
y
Grant access to any host on a specific subnetwork
For example, enter IP address 192.168.1.0 with netmask 255.255.255.0 to allow access to all
IPs on the subnet defined by this IP address/subnet mask combination.
y
Grant acces to all hosts
Make sure the accessible IP list is not enabled. Remove the checkmark from
