Prioritize Skype Traffic - Tomato QoS

    I am trying to prioritize Skype traffic on my Linksys WAP running Tomato. In several tutorials I have seen Skype traffic prioritized using a mac address or an IP or specific port number for Skype hardware devices. That really is not going to work well for me.

    I have several PCs running the Skype client all with different ports specified for incoming calls in Skype setup. I would like to prioritize all Skype traffic for all these PCs. I currently set this up using the L7 filter: skypetoskype. I've read that this is not ideal as the L7 filters are processor intensive. How should this be setup?

    It's not processor intensive that much, dont worry. I have a lot of L7 filter, and my cpu never was used more than 50% even when i used a lot of P2P.
    200MHz is plenty.

    Now I am really confused. I was under the impression that the processor use for L7 filters was on the router itself, not my local machine. Is that correct? If not, then how do I check utilization on a router? I have a Linksys WRT54GL.

    Of course it is on the router's processor.
    if you on windows:
    ctrl+c to exit top
    press any key

    if you are on linux, start a terminal, and the following is the same

    you can refresh top more frequently by starting it like
    top -d 1

    but then top uses more cpu (cc. 5%)

    There isn't really much choice in the matter, but be comforted - as you are a single user then you will not be pushing your router too hard - despite the L7 filters being processor intensive, you aren't using many of them.

    Actually there are 4 people on 4 PC's on this router and that was originally what concerned me about using L7 filtering. After talking a look at 'top', total CPU is ~15% or less even when I'm on a Skype call. I may add 1 or 2 more before I'm through. But as least now I know how to tell if I'm pushing it to hard. Thanks for the help!
