    Всем доброго вечера

    Есть домашний Zyxel ULTRA II. Есть туннель на работу. Появилась потребность посмотреть за этим роутером с работы. И получен отлуп. Совершенно странная ситуация опрос по SNMP одного и того же агрегата с одними и теми же параметрами:

    rtadmin@netxms4:~$ snmpwalk -v 2c -c public  10.10.15.1 .1.3.6
    iso.3.6.1.2.1.1.1.0 = STRING: "ZyXEL Keenetic Ultra II (NDMS 3.05.C.10.0-0): ku_rd"
    iso.3.6.1.2.1.1.2.0 = OID: iso.3.6.1.4.1
    iso.3.6.1.2.1.1.3.0 = Timeticks: (403880) 1:07:18.80
    << SNIP >>
    iso.3.6.1.4.1.2021.11.51.0 = Counter32: 0
    iso.3.6.1.4.1.2021.11.52.0 = Counter32: 19209
    iso.3.6.1.4.1.2021.11.53.0 = Counter32: 1574503
    iso.3.6.1.4.1.2021.11.59.0 = Counter32: 19092
    iso.3.6.1.4.1.2021.11.60.0 = Counter32: 48
    iso.3.6.1.4.1.2021.11.60.0 = No more variables left in this MIB View (It is past the end of the MIB tree)
    
    rtadmin@netxms4:~$ nxsnmpwalk -v 2c -c public  10.10.15.1 .1.3.6
    SNMP Error: Request timed out
    rtadmin@netxms4:~$

    Самое неприятное что так себя ведут два разных сервера с версиями 3.9 и 4.0. Опрос ноды из сервера дает тот же самый результат - тайм-аута и до свидания
    Проверялось все возможное - порты, community, правила МСЭб кастомные таймауты.

    Если бы не ответил на snmpwalk запросы тоже - я бы еще понял. Но на них то он отвечает!!!

    Куда копать?

      Я бы начал с дампа пакетов с помощью tcpdump или wireshark чтоб понять чем отличаются пакеты snmpwalk и nxsnmpwalk

        Во как. Ладно посмотрю дампы. Не хочется лезть в исходники, но тоже видимо придется.
        Вопрос ГДЕ еще это могло проявиться и как?  Не верю что мой дурацкий зюксель один так себя повел

          Ну если на машине, откуда посылаются запросы, несколько интерфейсов, то может с разных адресов запросы идут. IPv6 тут не должно быть - указан IPv4 адрес.
