Filter IPA Config and Operation

The Filter IPA table allows you to increase the NetGuardian's network security by allowing or blocking packets
from specified IP addresses. Addresses which appear in the table will be processed by the NetGuardian. Defined
IP addresses associated with network cameras or the network time server are automatically processed and will
not be filtered out by this feature. Broadcast packets of 255.255.255.255 and ARP requests for the NetGuardian
IP address are also not filtered.
1. From the Edit menu select Filter IPA.
2. A warning prompt will appear (see Figure 2.4.5.1). Click OK to continue, or Exit to cancel.
3. Once enabled, only the IP addresses in the table will be allowed access to the NetGuardian.
4. Select the Enable IPA Table box.
5. Enter the IP address of the machine(s) you would like to give access to the NetGuardian.
6. Click Submit to save the configuration settings.
