The following fields are displayed in the ACL – Add Filter window:
Criteria—filter type:
–
permit—Filter allows packets in a traffic flow if the filter conditions are met.
deny—Filter blocks packets in a traffic flow if the filter conditions are met.
– Protocol—Name or number of an IP protocol to apply an extended ACL filter to. To match any
Internet protocol (including ICMP, TCP, and UDP) use the keyword "ip". This argument is not
applicable when creating standard ACL filters, and mandatory for extended ACL filters.
– Source IP—Number of the network or host from which the packet is being sent.
– Source Mask—Bitmask used in combination with Source IP to specify a host address or a range
of addresses to apply filter. Place ones in the bit positions you want to ignore.
– Source Operand—Comparison operator for source TCP or UDP ports. The range operator
requires two source ports, all others require a single port. This is an optional argument that is
only applicable when creating extended ACL filters against TCP or UDP traffic. The following
values are available:
none
lessThan
equal
greaterThan
notEqual

Destination Mask—Bitmask used in combination with Destination IP to specify a host address
–
or a range of addresses to apply filter.
Destination Operand—Comparison operator for destination TCP or UDP ports.
