I'm looking to try and handle at least 4Gbit and 20,000 sessio= ns worth of PPPoE -> L2TP LAC traffic per server. The reading I've done fr= om the archives so far seems to indicate that this has not yet been done.. So my questions to you are: A) Can it be done? B) Am I crazy? C) What is the most sessions and traffic an MPD install is doing that you'r= e aware of? C) What kind of hardware is required? D) What MPD and BSD configurations would you recommend? E) How would I load test such a configuration? I'm hoping to start testing our options very shortly and am willing to cont= ribute development time & effort if required to make it happen. Thanks for= your help! -- Cheers! Dave
