oh this one i did not found before thanks a lot i gonna try it asap. Karol : yes this is not a law that ask me to log them but it is important to me that if a bad guy blackmail or threaten a client of mine i can track the ip+port so ISP can go up the chain to expose him. having ip+port is nothing more than ip we had for years before the ipv4 lack and Nat system started to appear so this is no more than we done since years. Just adapt it to the current situation. Karol: thanks, will have a look at postscreen too Thanks for all your answers. Best regards, Ghislain.
