• Safe Ports: Any port greater than 1024 (1025 – 65535) is considered a safe
port.
Dest Port: This specifies the Destination Port for the Inbound Policy. This is the
internal (WAN side, outside of the firewall) Port that will be affected by the policy.
See Src Port above for configuration detail.
Transport Protocol: This specifies the Transport/Transfer protocol for the policy.
The following protocol options are available: All, TCP, UDP, ICMP, AH, ESP, and
GRE.
Filtering Action: This specifies what action the policy takes:
• Allow: Selecting this will cause the policy to allow packet transfer from the Src
IP through the Src Port to travel through the Dest Port to the Dest IP. All of
these are specified above and must be configured by the user.
• Deny: Selecting this will cause the policy to deny packet transfer from the Src
IP through the Src Port to travel through the Dest Port to the Dest IP. All of
these are specified above and must be configured by the user.
Time Window Filtering: This field allows you to select a certain time frame from
the Time Group in which this policy will be active. See section 6.6 for more
information on Time Groups.
DB: Short for Database, this field allows you to select a user-defined IP Group for
the Src IP and Dest IP fields and a user-defined Service Group for the Dest Port.
Userdefined IP and Service Groups are created in IP Group and Service Group
pages, sections 6.4 and 6.5, respectively..
