BreezeMAX Modular Base Station System Manual 231
The L3/L4 Filtering Rules menu enables defining new L3/L4 Filtering Rule,
viewing details of previously defined L3/L4 Filtering Rules and removing L3/L4
Filtering Rules from the database. It is not possible to edit the parameters of an
existing L3/L4 Filtering Rule. The database can hold up to 255 L3/L4 Filtering
Rules.
The configurable L3/L4 Filtering Rule parameters are:
4.11.4.8.2.1 Rule Name
The name of the L3/L4 Rule. The L3/L4 Rule Name is a string of 1 to 32 printable
characters.
4.11.4.8.2.2 IP Address
The base IP Address that is used together with the IP Address Mask to define a
range of IP addresses. A string of 4 decimal numbers (where each number is in the
range from 1 to 255) separated by dashes ("-"). An empty entry means "Any". An
"Any" IP Address means that the filter is defined only by the Protocol field (and
optionally by the Port and Port Direction for UDP or TCP protocols).
4.11.4.8.2.3 IP Address Mask
The mask that is used together with the IP Address to define a range of IP
addresses. A string of 4 decimal numbers (where each number is in the range
from 1 to 255) separated by dashes ("-"). In a binary representation, the string
must comprise a series of contiguous binary '1's starting from the MSB, followed
by a series of contiguous binary '0's (if the range includes more than a single
address). The IP Address Mask parameter is not applicable to an "Any" IP Address.
4.11.4.8.2.4 IP Address Direction
The direction (Source or Destination) of the IP Address. Indicates whether the
range defined by the IP Address and IP Address Mask is for the Source IP Address
field or the Destination IP Address field in the IP frame. The IP Address Direction
parameter is not applicable to "Any" IP Address.
4.11.4.8.2.5 Protocol
The protocol of the IP packet. The Protocol is defined by a decimal number from 0
to 254. An empty entry means "Any" and is applicable only if an IP Address range
is defined (the combination of "Any" for both the IP Address and Protocol is not
allowed).
4.11.4.8.2.6 Port
The TDP/UCP port number, which is applicable only if the Protocol parameter is
configured to a value of either 6 (TCP) or 17 (UDP). The Port is defined by a
number in the range from 0 to 65534. An empty entry means "Any" port.
