You can police in-bound as well, but as you point out, the problem is that the congestion has already occurred at that point.
Basically, this is more a political problem than a technical one. You need to limit (in some fashion) either at or behind the ISP router in Germany. Talk nicely to them. Buy a techie over there some beer. Whatever makes it work! If you have some of your gear on the other side someplace, then make limitations there. But first I would try to figure out just what traffic is causing the congestion and determine whether it's random packets, port scans or some legitimate type of traffic. That will help you determine which path you are talking about! HTH, Scott Morris, CCIE4 (R&S/ISP-Dial/Security/Service Provider) #4713, JNCIE-M #153, JNCIS-ER, CISSP, et al.

I was reading with the goal of being able to apply it. The problem is that the the Internet connection uses different RX and TX paths (satellite DVB/SCPC link) and so as far as the edge router (a Cisco 1760) is concerned - no traffic ever comes in through the serial interface (that is connected to a satellite modem) and no traffic ever leaves the router through the fastethernet interface (connected to a switch to which the DVB and other nodes with public ip addresses connect) My problem is this ... how can I provide some QoS given that the link that suffers congestion (the satellite link) is not within my control. According to documentation, you can only apply LLQ outbound from an interface (not an option to me ... cos that interface is on an ISP router in Germany). My DVB receiver is an appliance which doesn't have any way to configure QoS on. I know i can do traffic caching on a server behind the router but i would love some solution that utilizes my cisco equipment. I will appreciate any suggestions ____________________________________________________________________________ _______________________________________ "A man owns nothing, not land or money, only his character, the loyalty & courage in his heart" My Bogs: ICT Business [Integration] - http://ibiztech.wordpress.com [Leadership Lessons from Movies] - http://thbs.wordpress.com [In Search of Excellence & Perfection] - http://mukom-tamon.blogspot.com
