Thanks for your fast answers,
I know that TCP over TCP is a bad idea it create uneeded traffic, but it
was need (tcp with 433)
as for bcast-buffer I set it higher, hopefully that will help. I do not
know if the buf packet drop is happening becaus eof FTP but we jus noticed
it when one of my colleague was using FTP. I have seen other computer
having mbuf drop but I do not have the hand on it.
