Prioritize client's traffic

[omie48]

I've been trying to use the traffic shaper to prioritize one local client's traffic to and from the WAN above all others, but I'm struggling.

I've just deleted all my traffic shaper rules again as I don't know if any of it was remotely right.  Could someone please show me how the traffic shaper could be configured to simply prioritize a single client's traffic above all others?

2 Pipes, in an out with max band minus some percent. 2 queues, in and out, one weight 80, one weight 20. Rules for one IP source and dest with 80, rules for LAN with higher ID for 20, always up/down
