Strange Upload or broadcast??

[Net_Spy]

Greetings to All,

I'm having a strange problem , Here is the scenario that I'm running currently , I've two NIC 1 is for wan and 1 is for lan . I've created virtual interface to route IP pool for my clients ( Real IP globally accessable) . Now the problem is that when any of their clients create wheather broadcast or upload , when I logged into their machine n run iptaraf I found 1 or 2 ip from their local area having outrate more then their actual bandwidth let say eth0:(wan) 2mb and eth1: it goes up to (10mb) they have full control on upload it is 128kbps using cbq. That disturb my interface aswell which it should not be happed I think. Any idea to resolve this issue ?? Looking forward for your kind response.
