heres a question lake....sorry if it noone understand but,....client<-->proxy<-->server right?

proxydont work cus client and server speak differently to each other(f306 changed)and the prox is just a filter of sorts..now lets say you use wpe(i know its worthless cus of encryption,but for example)to send the prox the old f306(i know packets are different everytime cus the 3/4 keys change,but again for example) to make it autohunt?or will it still not understand cus of the packet change (like dont understand where the monstersare)?SORRY I KNOW THIS IS A QUESTION AND IN THE WRONG FORUM...i dont understand the new packets.i wish somone would make a guide or a post on whats different and why(i understand the old packets,and the new ones confuse the hell out of me cus i dont know everything they changed.thank you
