 Здравствуй  All
 Столкнулся с непонятной проблемой.
 Машина с Linux-Mandrake 2.2.17
 Два интерфейса
 eth0  192.168.1.0
 eth1  192.91.148.6  соединен с удаленным 192.91.148.5
 
 Ping самого eth1 проходит успешно.
 Удаленный интерфейс, судя по tcpdump  в соседней консоли, отвечает
 HО ответа для Ping не приходит.
 Где могла собака порыться ?
 ipchains пустой.
 
 Буду благодарен за любой намек.
