I had a large syn flood which was about 7 mbps incomming. The server also sent 7 mbps outgoing to reply to those syn's. How can i stop that or somehow rate limit to maybe 500 kbps or 1 mbps? I'm not able to find an option to do this using ipfw and/or dummynet. Thanks. Holt __________________________________________________ Do You Yahoo!? Yahoo! Shopping - Thousands of Stores.
