I'm interested in stress testing my gateway server but am lost on how. Most of the stress testing applications I've seen only see how much load an app like Apache can handle, but not this.
Essentially I want to send as many packets I can into this box with one computer on one card and see how many come out the other in another computer just to get an idea of what kind of load this can handle. I'm also interested how Snort will perform. I'm not really sure how to do this though.
What tools could you recommend that could do this?
