I have been trying to tweak my QOS tonight and just read more about the "Connection Bytes" field. Below is what I'm trying to accomplish followed by how I set up my download rules. Will someone please verify that I have configured them correctly or make suggestions if not?
My 4 Classes

What I'm Wanting
- GameStreaming to be a top priority (1723)
- HTTP / HTTPS browsing to be a top priority (80/443)
- HTTP / HTTPS Downloads (traffic to same site over 1mb) to be lowest Priority (80/443)
- Remote Desktop to be top priority (3389?)
RDP is 3389 by default - but I forward the port to a different WAN port. I have the rule set as destination for 3389. Is this correct or do I need to add the custom external port somewhere as well?
- DNS to be a top priority (53)
- FTP browsing to be a top priority (21)
(Browsing and listing directories)
- FTP downloads (over 2 mb between same site) to be Normal priority (21)
I rarely have FTP and HTTPS downloads running at the same time - but - when I do I want FTP to have the edge. That's the only reason I added this class.
- Plex to be a top priority (32400)
My Rules

The three main things I do from my machines are FTP downloads, HTTPS downloads, and media streaming. I've obviously matched their importance to me in the rules above.
Please let me know what you think or if I need to make any changes. Thanks!
