QoS in a LAN-port only environment

    Please help!

    I have a unique situation and am having difficulty implementing QoS with Tomato (and previously with DD-WRT for that matter), and I suspect it may have to do with my configuration.

    Because I use Sonicwall TZ-170 firewalls on multiple sites, and do site-to-site VPN with those boxes (and cannot get rid of them), I must use the LAN ports only on my Buffalo WHR-HP-G54. Both the Sonicwall and the Buffalo are on the same subnet mask (192.168.0.1). The Buffalo's LAN IP is 192.16.0.76.

    I have not been able to get QoS to work. I use Vonage VoIP and also a business-to-business VoIP phone system. I have put the port numbers the phone system uses up to the "Highest" priority, and have also put the MAC address of the Vonage box to the "Highest" as well. I have put BitTorrent/uTorrent traffic down at the bottom and list it as "Bulk".

    Despite these efforts, when I use uTorrent and and upload/download a large file, there is noticeable breaking up on phoe calls. When I look the the QoS graphs in Tomato, all traffic appears as Unclassified (100%). And the Outbound Traffic all shows as 0%.

    Does anyone have any ideas? I have spent 2 weekends on this and cannot figure it out!

    One other thing I would like to emphasize -- I need priority not just on Vonage, but also on the phone system's VoIP card as well. There is a lot of site-to-site conversation over the phone system's internal card that does not even involve the Vonage line.

    Thanks in advance!

    I believe local traffic is handled by the switch, doesn't touch the Linux routing - so QOS won't work.

    QoS only works for traffic passing from vlan0 (LAN) to vlan1 (WAN). So, you need a QoS enabled switch - or you create different vlans on the tomato (manually) and then set up routing and qos in between (also all manually) - I guess that's not what you're looking for and there are affordable QoS enabled switches with a web interface that let you configure QoS in a similar way than you can with Tomato.
