I think the easiest and most robust way to shape ingress traffic for you
would be to do it on the LAN side.
If you have multiple interfaces facing LAN then use ifb.
I've never used it myself, but to mark multiple address ranges the
easiest way would be to use iptables with ipset - there will be many
examples to be found on the internet.
Even if you do mark (well set dscp cs1) for steam servers you will still
need to be backed off from your ingress rate enough or it still won't
work as the queue will build up too much on the ISP side of the
bottleneck. Shaping ingress is quite different to doing egress as you
are at the wrong end of the bottleneck.
