Filters-Inbound:Use IP Inbound Filters to deny WAN IP addresses from accessing the internal network. You can deny specific port numbers or all ports for the specific IP address.

Source IP: IP address criteria for the source computer(s) from which the packet originates.

Destination IP: IP address rule criteria for the destination computer(s) (i.e., the IP address of the computer to which the packet is being sent).

Source Port: Port number criteria for the computer(s) from which the packet originates. This field will be dimmed (unavailable for entry) unless you have selected TCP or UDP as the protocol. See the description of Source IP Address for the selection option.

Destination Port: Port number criteria for the computer(s) (i.e., the port number of the type of computer to which the packet is being sent). This field will be dimmed (unavailable for entry) unless you have selected TCP or UDP as the protocol. See the description of Source IP Address for the selection option.

Protocol: drop down menu allows you to select the transport protocol for this access policy. If the desired transport protocol is not listed in the menu, then you can chose "OTHER" option and enter the desired IP based transport protocol number in the following text box.

Reverse NAT: Normal NAT is performed for the packets that travel from internal network to the External network. If we configure NAT for an outbound policy then NAT is performed and if NAT record is configured to an inbound policy then reverse NAT will be performed. Basically, when traffic is destined to the box from external network, then firewall searches for the presence of any inbound policy with NAT configured. Reverse NAT item is Disable by default. You can enable or disable NAT by selecting the Enable or Disable option in the configuration menu and submitting the settings.

Action: menu helps in defining this policy as Permit or Deny type policy. Permit type policies allow the traffic matched by the policy selectors to pass through, where as Deny type policy blocks that traffic.

Schedule: This is following Schedule Configuration. Default setting is None. When Schedule Configuration add new time schedule, this item will follow new time schedule item.
