Question

Доброго дня!

Собственно, эксперименты с изменением TTL на интерфейсе LTE-шного свистка. Никаких ошибок, но и никаких результатов...

А что вы ожидаете от пинга?

В ответе ttl отвечающего.

Он в одном хопе от меня. Для информации. Вариант следующий. Свисток заменен:

TTL кинетика не модифицирован, зато хуавей запилен как надо и на нем TTL выставлен в 129. Результат:

Винда за кинетиком:

Как-то так...
