    I've seen many rules of thumb and stuff listed here in the past. I just got alchemy going and watned to know what is the proper way to set it up?

    Only 3 boxes:
    Port 1 Gamer box (always needs low pings)
    Port 2 wife box (just likes to browse and download songs)
    Port 3 web server (no one visits me, its moslyt for development :)

    I have 1500/768 DSL

    All I've done so far is assign the gaming box to premium, and the other 2 to standard

    Do you leave the download field blank and upload at 75-90% of your capacity or fill in a value for download too?

    fill in the download box.
    run a few speed tests and use that as gauge.
    my speed with cable fluctuates I've got a 5000/800 connection but depending on traffic I get anywhere from 3000/240 to 6000+/900+ -- I don't think you should have this problem with DSL though. You want the software to start QoS'ing (sharing or allocating bandwidth if we can call it that) at whatever download speed you specify. otherwise your wife can be maxing out your download speed using very little upload speed -- and your gaming PC will just have upload bandwidth for itself. I didn't write the Alchemy software but that's how I think it works.
    anyone else on this topic?

    well since your PC is the main priority set port 1 to premuim. set the rest to bulk/standard should do the trick

    you could also if you use static IP to set IP priorities if you wanted.

    are you still having problems?

    ya I'm getting wierd results

    I used my local hub to test speed and got 1256/628 repeatedly

    [edit oops nm about the limiting, i put them reversed :(]

    I have mine as premium and all others set to bulk

    for the netmask priorities, what does the /[0-32] signifiy?

    Add (the zeros are all boxes)

    I take it alchemy checks ip rules then mac then port first and ip based is most desireable?

    assuming my theoretical limit is 1256/628
    when i put in 1000 for download and 600 for upload, does that mean no single computer on the network can go past that speed?

    the /x indicates the subnet or the range of ips effected.
    using ip.ip.ip.0/24 will include the whole class C using a /32 will include a single computer...

    these are netmasks for ranges of IP addresses.

    A single IP address /32 (ie which is only)

    A range of IP addresses /30 ( which is to )

    A range of IP addresses /28 ( which is to

    A range of IP addresses /26 ( which is to

    A range of addresses /24 ( which is to
