I found the way to find the location of the servers thanks to dscptag of dlakelan in ruleset-post but I would like to use just the option udp meter4 and something which generates the server at the beginning of game at the time of the connection to the server on line of the game call of duty that works very well it is genial but I would like to launch it automatically has each game via ssh to see if the waiters evolve or change, I put you in link the script of dlakelan and the handling to carry out this turn of pass

then /etc/init.d/firewall restart
then connect to the game connexion service in line
then just "nft list ruleset" ## in ssh
