Hello,

Thanks for explainning the reason for udp ports not appearing in the
tcpdump output.
Well the Cisco 3750 is the gateway for my clients and not the
destination host (so I can't figure why it starts choking)

The source IP addresses belong to my clients (those with 86.104 ).

And it usually happens like this:
3/4 ip addresses that belong to my clients contact the same 4-5 ip
addresses like the one below (70.84.247.164) and start doing 98% only
upload udp traffic.

Is it possibly for a service to do so much upload compared to download ?

May be this is not the right question. You'd should rather question "what
the hell is talking to 70.84.247.164?"

And 98% upstream udp ist strange in the second step.
