на фре установлен pf, squid (sams + rejik)
но не совсем понимаю что к чему....
необходимо:
оптимизировать (убрать лишнее)
максимально обезопасить (убедится, что дырок для пробных и не пробных атак минимальное количество и все под контролем)
сделать возможным обновление винды (лицензия) из сети
сделать возможным обновление drWeb (лицензия) из сети
