User's Manual
Defines the maximum allowed packet size.
The valid range is 0 to 65535.
Note: When filtering fragmented IP packets, this field relates to
the overall (re-assembled) packet size, and not to the size of
each fragment.
Defines the expected traffic rate (bytes per second), i.e., the
allowed bandwidth for the specified protocol. In addition to this
field, the 'Burst Bytes' field provides additional allowance such
that momentary bursts of data may utilize more than the
defined byte rate, without being interrupted.
For example, if 'Byte Rate' is set to 40000 and 'Burst Bytes' to
50000, then this implies the following: the allowed bandwidth is
40000 bytes/sec with extra allowance of 50000 bytes; if, for
example, the actual traffic rate is 45000 bytes/sec, then this
allowance would be consumed within 10 seconds, after which
all traffic exceeding the allocated 40000 bytes/sec is dropped.
If the actual traffic rate then slowed to 30000 bytes/sec, then
the allowance would be replenished within 5 seconds.
Defines the tolerance of traffic rate limit (number of bytes).
The default is 0.
Defines the firewall action to be performed upon rule match.

"Allow" = (Default) Permits these packets

"Block" = Rejects these packets
