To apply rules:
1.
Use the screen section 'Matching' to define a match between IP addresses and a
traffic protocol.
2.
Configure the source address of the packets sent to or received from the network
object (computer A in the above example). To add an address, select the option
'Specify Address' from the drop-down list; the screen refreshes and a link 'Add'
appears (refer to the figure).

3.
Click the link 'Add'; this commences a sequence that adds a new network object.
4.
Configure the destination address of the packets sent to or received from the network
object. This address can be configured in the same manner as the source address.
5.
Choose a specific traffic protocol from the 'Protocol' drop-down list or add a new one.
To add a new traffic protocol, choose the 'Specify Protocol' option in the drop-down
list; the screen refreshes and a link 'Add' appears (refer to the figure).

6.
Click the link 'Add'; this commences a sequence that adds a new protocol.
7.
In the screen section 'Operation', define what action the rule will take; check one of the
following radio buttons:
•
Drop - Deny access to packets that match the source and destination IP
addresses and service ports defined in 'Matching'.
•
Reject - Deny access to packets that match the source and destination IP
addresses and service ports defined in 'Matching' and sends and sends an ICMP
error or a TCP reset to the origination peer.
•
Accept - Allow access to packets that match the source and destination IP
addresses and service ports defined in 'Matching'. The data transfer session will
be handled using Stateful Packet Inspection (SPI).
•
Accept Packet - Allow access to packets that match the source and destination IP
addresses and service ports defined in 'Matching'. The data transfer session will
not be handled using Stateful Packet Inspection (SPI), meaning that other
packets that match this rule will not be automatically allowed access. For
example, this can useful when creating rules that allow broadcasting.
•
QoS - Select this check-box to define QoS Operation for the rule (the following
section).
