ONE or TWO ADSL ??

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?
