You can Delete or Edit a packet filter rule after it has been defined and added by using the table at the bottom of the 
screen.  

 

Enter the network/host from which the packet must originate for the filter rule to 

match. The Any option, which matches all IP addresses regardless of whether they are 
officially assigned addresses or private addresses, may also be entered. The 
network/host must be pre-defined in the Networks section. 

Enter the service that is to be matched with the filter rule. These services must be pre-
defined in the Services section. These services precisely define the traffic to be filtered. 

Enter the network/host to which the packet must send for the filter rule to match. The 

Any option, which matches all IP addresses regardless of whether they are officially 
assigned addresses or private addresses, may also be entered. The network/host must 
be pre-defined in the Networks section. 

Enter the action that the packet filter executes if the rule matches any traffic traversing 
the firewall. Types of actions defined are: 

 Allows/accepts all packets that match this rule. 

 Blocks all packets that match this rule. The host sending the packet will be 

informed that the packet has been rejected. 

 Blocks all packets that match this rule, but the host is not informed; i.e., this is a 

silent drop. 

 Packets matching the rule; i.e., the corresponding source address, destination 

address, and service will be logged. 

 Click 

the 

Add button. The defined packet filter rule is added and will display at the 

bottom of the screen.
