NTA supports two types of filters for each filter condition: the discard filter, which discards any
packet that matches the filter conditions specified, and the receive filter that processes and reports
on any packet that matches the filter conditions.
7.
Select Discard from the Policy list if you want NTA to discard any packet that matches the specified
filter conditions.
Select Receive from the list if you want NTA to process and include in reporting any packet that
matches the filter conditions.
NOTE:
At least one of the filter conditions you create must differ in policy from the Default Policy. For example, if
you set Receive all packets as the default policy for the filter strategy, then you must create at least one filter
condition that has Discard as its filter policy.
8.
Enter the IP or IPv6 address and subnet mask in the Source Host field, if any, which are used to
match the source IP address contents of all IP packets processed by this filter condition. This field
is optional. Leaving this field blank directs NTA not to filter any packet by source address.
This field is optional and leaving this field blank directs NTA not to filter any packet by source
address.
An IP address or an IP address and subnet mask for a range can be entered in dotted decimal
notation or CIDR notation, using a backward slash (/) to separate the IP address from the subnet
mask.
An example of a valid IP address entry:
10.153.89.10
An example of a valid network/subnet mask in dotted decimal notation:
10.153.89.0/255.255.255.0
A valid network/subnet mask entry using CIDR notation:
10.153.89.0/24
A valid IPv4 address entry can be an IP segment. An example:
1.1.1.1-1.1.1.100
An example of a valid IPv6 address entry:
a001:410:0:1::1
A valid IPv6 address and subnet mask using CIDR notation:
a001:410:0:1::1/64
A valid IPv6 address entry can be an IP segment. An example:
a001:410:0:1::1- a001:410:0:1::100
9.
Enter the Layer 4 port number in the Source Port field, if any, that is used to match the source port
contents of all IP packets processed by this filter condition.
This field is optional and leaving this field blank directs NTA not to filter any packet by source port
number.
10.
Enter the IP or IPv6 address in the Destination Host field, if any, that is used to match the destination
IP address contents of all IP packets processed by this filter condition.
This field is optional and leaving this field blank directs NTA not to filter any packet by destination
address.
An IP address and subnet mask can be entered in dotted decimal notation or CIDR notation, using
a backward slash (/) to separate the IP address from the subnet mask.
An example of a valid IP address entry:
