Chain Rule:
The chain rule determines whether the access from the hosts is allowed or not. It can be one of the these two
values:
ACCEPT:
access allowed
DROP: access not allowed
When the IPCS receives a TCP packet, it will process the packet with the chain rule depicted below. The process
ordering is important; the packet will enter the chain rule 1 first, if meet the rule then take action directly,
otherwise go to chain rule 2.
Users can add new IP filtering rule by setting the properties at adding line and then clicking the button Add.
User can remove a rule by clicking the button Remove.
