"Нормально получать столько ICMP UNREACHABLE в свою сеть?!"
Отправлено TrEK, 26-Ноя-09 11:03

Всем привет... получаю icmp unreachable на запрашуемные сайты с своей сети от айпи 10.11.128.30 ... которая является вторым хопом после провайдера.
Что это означает... сайты , на которые недоступность возвращаетьсья, не открываются соответсвенно.
С чем связаный такой недуг?
