1) Ваше сообщение меня поставило на грань шизофрении. Долго думал. Решил, проверить почти нереальное:
Подключаемся через телнет:
Код:
madgnu@andromeda:~$ telnet 172.30.0.254
Trying 172.30.0.254...
Connected to 172.30.0.254.

Потом смотрим в окне телнета:

И все-таки я не шизофреник :)
2) Да, для организации downlink-а. Проблема в том, что там периодически может попадаться неуправляемое/недонастроенное оборудование по не совсем зависящим от меня причинам (и я даже об этом узнать смогу только постфактум при возникнавении проблемы).
