Se requiere el aprovisionamiento manual de reglas de firewall para una instancia de dispositivo aislado de Google Distributed Cloud (GDC) debido a la asignación estática de la red de administración junto con la huella mínima de tráfico de red.
Debes aplicar de forma manual las políticas de firewall basadas en el host para los flujos de tráfico de red en la red de administración del dispositivo aislado de GDC. Para aplicar reglas de filtrado de puertos y de IP en las interfaces de red de las máquinas de metal, usa la biblioteca de comandos de Uncomplicated Firewall (ufw).
Aplica reglas de firewall
La red de administración del dispositivo aislado de GDC es eno1. Las direcciones IP estáticas de las máquinas del dispositivo aislado de GDC son las siguientes:
Nombre de la máquina
Dirección IP
xx-aa-bm01
198.18.255.228 (administrador raíz o administrador de la organización)
xx-aa-bm02
198.18.255.229
xx-aa-bm03
198.18.255.230
Para aplicar las reglas de firewall a la red de administración, sigue estos pasos:
Establece una conexión de Secure Shell (SSH) desde la máquina o la laptop de arranque a la máquina bm01 con la clave SSH predeterminada que proporciona Google.
ssh198.18.255.228
Configura las rutas predeterminadas en la interfaz de administración de bm01:
Configura las políticas en los nodos de administrador raíz bm01. Estas políticas permiten el tráfico en la lista de entidades permitidas en la red de administración entre los distintos dispositivos del dispositivo aislado de GDC. Las políticas también permiten el acceso a SSH desde todas las máquinas físicas, junto con la máquina o la laptop de arranque:
Establece una conexión de Secure Shell (SSH) desde la máquina o laptop de arranque a la máquina bm02 con la clave SSH predeterminada que proporciona Google.
ssh198.18.255.229
Configura las rutas predeterminadas en la interfaz de administración de bm02:
Establece una conexión de Secure Shell (SSH) desde la máquina o la laptop de arranque a la máquina bm03 con la clave SSH predeterminada que proporciona Google.
ssh198.18.255.230
Configura las rutas predeterminadas en la interfaz de administración de bm03:
