PCQ

Hi
I have a question about PCQ picture. http://wiki.mikrotik.com/wiki/File:PCQ_Example1.png
I think two src address and destination address for pcq classifaier should be same for upload and download
for example for a packet when go out from our network src address is 192.168.0.1 (upload) and when come to our network dst is 192.168.0.1 .
I confuse with this picture. can you help me?
thanx

When you download file:

Internet → Your device (dst-address is address of your device)

When you upload file:

Internet ← Your device (src-address is address of your device)

If you want to limit concrete client then you need to check traffic based on dst-address when it is download and based on src-address when it is upload.

In example you can see only one direction traffic. In example src-address is “Your device” address and dst-address is Internet (not the Internet but simply to compare it with my example).
