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. -- "Theoretisch ist es praktisch, aber praktisch ist es unpraktisch" Bernhard P.
