Так, ни одной патологии я не обнаружил. Все очень читенько и
акуратненько.
Причем пакеты явно уходят, но ни один из них не возвращается...
Черт, очень похоже, что Вы включили фаерволл с полным запретом на
все пакеты!
Плиз, Kurt, от root'а, дайте вывод команды:
ipchains -L -v
а если ее нет или еще чего то, то попробуйте команду:
iptables -L -v
Для окончательного диагноза будет достаточно увидеть вывод хотя
бы одной из этих команд.
