Line speeds are *usually* measured in bits per second.  Also, "k"
means kilo, not kibi.  So, your line speed will probably be:
   256000 bits per second
or  32000 octets per second.

> If I have the following line in the .CFG (MaxBytes[x.x.x.x_5]: 256000)

MaxBytes should be the number of bytes (octets) per second so if above
numbers are correct, you should put 32000 in there, not 256000.

You didn't specify "bits" so all speeds are shown in bytes, this is
what you want.

Please talk the right language here.  "kb" is commonly known to be
"kilobits" and this is "1000 bits".  From the context I know you mean
bytes however this is usually written as "B".
So: your line speed is 32kBps or 256kbps.

And while you are changing, please keep the length of your lines
below 72 chars when writing an email.  You're on the internet, not
on your local lan. Thanks.
