Hi, I am Yoni, the office guy here, not the programmer. We are using JnetPcap. We could use some paid-for help to move forward with our packet problem, want to divert packets for the purpose of pre-processing, and return them to the stream. This is in part what this API is supposed to do, right? Somebody who is an expert with this API could earn a few bucks of you want to volunteer to help. Please contact me through this forum, or tel. (650)331 1618; or johnnydawson@gmail.com. THANKS!
