Красивый эффект...
Из подсказки к fiaif:
"ECN (Explicit Congestion Notification) is defined in RFC3168. It allows
routers on the internet to notify when congestion occurs, and can avoid
packet being dropped due to queue overflow. Overall this is good for
the internet.
The backside is that some really brain-damaged firewalls and routers
do not allow packets with the ECN bit set (and thus not conforming to
RFC3168)."

Вот это действительно вопрос. Я тоже на машинах с ALT видел
по-умолчанию только tcp_ecn=0. Специально переключаю на 1, и
пока проблемами не сталкивался.
