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
