    Hi,

    I have one ADSL like most people for personal use....
    I am running a Webserver on a different machine.
    My ADSL : ~700kb upstream

    If somebody is downloading something, the communication start to be crap
    I prioritized the com. I force my Asterisk server to use TOS=0xb8, in
    order to select these packets.... but this is not great
    I check and I have all my RTP packets, market with TOS=0xb8 (DSCP=0x2e)

    Do you have a trick ?
    I was told to have 2 ADSL like companies... that I don't want for
    personal use
    - Should I use a Linux machine managing IPTables (I would be maybe
    luckier !?)

    What do you think ?

    Thanks

    Does your router support QOS (You neglected to tell us which router you
    have) Perhaps you could try a router with QOS like a Zyxel 660H

    I think you would be best off running the web-server on a hosted domain
    rather than your domestic ADSL connection.
    It would cost less than having a second ADSL connection and give far
    better connection speeds for people connecting to your server.

    I found QOS as applied by the modem/router (Draytek) OK, but still gives
    rise to occasional voip conversation problems. As such, at work, added a
    2nd ADSL line on a PAYG tariff purely for VOIP. But it also serves as a
    fail-over should the main ADSL provider go tits-up (and vice versa)

    I'm not sure how effective ToS bit manipulation is; it depends on every
    device in the chain honouring it for it to work. However, egress bandwidth
    is something you /definitely/ have control over, so is probably a more
    fruitful place to look.

    Linux can do traffic shaping/QoS. You could make your Asterisk box the
    gateway on your network and manage the QoS there.
    http://lartc.org/wondershaper/ is a good starting point for QoS on Linux.
    Presumably whatever gateway you have at the moment doesn't do QoS,
    otherwise you wouldn't be asking?
