Похоже, ICMP у них еще где-то внутри режется, но с работы у меня, по крайней мере, туда коннект устанавливается. А со стрима - нет.

А почему только на dal.net?
На 2600.net пускают, на efnet тоже, а вот лично dalnet почему-то не любят.

Ну и вопросы ты задаешь, дядь Саш... хотя я, конечно, могу ответить "хуй его знает" :-)

Я задал вопрос в поддержку стрима. Глядишь, чего и ответят.
А я пока зашел через matrix.de.eu.dal.net - он в другой сетке, туда пустили.

Просто у мту и саввиса этого provider independent с префиксом /24 нет в bgp, и они не знают, куда его роутить.
