Basically what I want is my gaming getting a minimum slice of the bandwidth, while any other device gets the rest. Here is what I have so far.
Gaming class:

Default class:

Now for the classification rules. The only ones I think I need to set up are for my gaming devices, as it says all other devices that don't meet the criteria will be put in my default class. For example, I followed the guide by going into connection>DHCP and gave my PS4 a static IP address. Does the rest of the information in this form need to be filled out besides the IP address of the PS4 in the destination IP section?

The classes and service rules from the QoS downloading section seem identical to that of the uploading section. The only difference I know I need to do is instead of putting the PS4 IP address in the destination section, I need to put it in the source IP section for uploading. In terms of the active congestion control, can I just check the box to enable it and roll with that (is there a need to fill out the "use non-standard ping target" or "manually control ping targets")? Thanks for the help.
