PCC - Question on per-connection-classifier=both-addresses

RouterOS General

Hi

I have a question regarding per-connection-classifier=both-addresses:

If I am spreading load over 2 Lines I would expect to see something like the below.

add chain=prerouting in-interface=LAN connection-mark=no-mark dst-address-type=!local
per-connection-classifier=both-addresses:2/0 action=mark-connection new-connection-

What does the number after the / refer to? I understand I can place extra marks, to cater for non equal lines, but can the 2nd number be greater than the 1st? For example, could you have 2/4? I can find no reference to this in the WiKi.

per-connection-classifier=both-addresses:Y/X

Divide by Y, X is the remainder
Valid values for X will be 0 through Y-1.

Lets say the hash comes up with a 6 for a given packet based off of the source and destination addresses and then 5 for another.
6 divided by 2 leaves no remainder, thus your rule would affect this packet
5 divided by 2 leaves 1 for the remainder, thus in order to affect the second packet you would need a rule such as below:

per-connection-classifier=both-addresses:2/1

Many thanks for taking the time to explain.
