Creating a Network Filter
The
Active Network Access Filters
table on the
Network Filters
page displays currently defined filters.
These filters control if access to the NSS from specified hosts is granted or denied on a per-protocol
basis. Each device in your network is assigned a fixed 48-bit MAC address and changeable 32-bit
IP address. When you define a filter, it grants or denies access via the specified protocol from the
specified IP/MAC address or range of IP addresses.
To add a network filter:
1. From the
Manager Menu,
click
Access
Network.
The
Network Filters
page appears.
2. From the
New Network Access Filter
table, type the IP/MAC address to which you are applying
the filter, in the
IP/MAC address
field. You can also enter addresses for the following:
•
An IP Address Range:
Type the range according to the following format:
first address-last
address
. (Where the first IP address in the range is entered first, followed by a hyphen, and
then the last IP address in the range.)
•
A Subnet:
Enter the subnet to set a filter for all the addresses within the subnet. The format
should appear as shown in the following example: 192.168.1.0/24 (where the digits
following the slash represent the number of bits in the network portion of the IP address).
