To configure advanced filtering rules, click Add next to the rule title. The “Add
Advanced Filter” screen appears.
To add an advanced filtering rule, define the following rule parameters:
Matching
To apply a firewall rule, a match must be made between IP addresses or ranges
and ports. Use the “Source Address” and “Destination Address” drop-down lists to
define the coupling of source and destination traffic. Port matching will be defined
when selecting protocols. For example, if the
FTP protocol is selected, port 21 will be
checked for matching traffic flow between the defined source and destination IP s.
Operation

radio buttons:
s IP

addresses and protocol ports defined in upper section of the screen. The
