    Глюки dhcp relay

    in 2.12

    Posted

    Подскажите пожалуйста столкнулся с проблемой предположительно сбоя системы dhcp relay. ДАНО: Keenetic ii подключен в локальной сети через интерфейс wan. Настройки роутера:

      

    !
interface Bridge0
    rename Home
    description "Home network (Wired and wireless hosts)"
    inherit FastEthernet0/Vlan1
    include AccessPoint
    security-level private
    ip address 192.168.1.11 255.255.254.0
    ip dhcp client dns-routes
    ip dhcp client name-servers
    igmp downstream
    up
!
ip dhcp pool _WEBADMIN
    enable
!
ip dhcp pool _WEBADMIN_GUEST_AP
    range 10.1.30.33 10.1.30.52
    bind GuestWiFi
    enable
!
ip dhcp relay lan Home
ip dhcp relay wan ISP
ip dhcp relay server 192.168.10.1
ip http port 80
ip http security-level public
ip http lockout-policy 5 15 3
ip http ssl enable
ip http ssl redirect
ip nat GuestWiFi
ip nat sstp
ip telnet
    port 23
    security-level private
    lockout-policy 5 15 3

    DHCP выключен на кинетике, получает от сервера в локальной сети. Но подключаемые через кинетик устройства на минуту получают ip адрес, а потом пропадают из списка устройств. Лог:

    Аналогичная ситуация не только с этим клиентом. Клиенты по вай-фай также имеют проблемы.

    Все нормально работает нормально ровно 1 раз. СТоит перегрузить клиента, либо устройство - больше не работает.
