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 Enable the

accessible IP list.

The following table shows additional configuration examples:
