Important Note about the Order of Rules:
The order of the rules in the table is essential for the correct functioning of the firewall. By clicking the Move button, the order of execution can be changed. In front of rule to be moved, enter the line number that indicates where the rule should be placed. Confirm by clicking OK.

Select the action that packet filter executes if the rule matches any traffic traversing the RouteFinder firewall. There are four types of actions:

•Reject – Blocks all packets that match this rule. The host sending the packet will be informed that the packet has been rejected.
•Drop – Drops all packets that match this rule, but the host is not informed. It will appear to the host that the destination address is not responding; in other words, it is a silent drop.
•Log – Packets matching the rule will be logged. Source address, destination address, and service will be logged. The logged messages are routed to the Remote Syslog Server if enabled in the Administration section.
