Warum ist OMV nur auf IP 10 erreichbar ?

• Debian Trixie Image …
• VM anlegen mit Bridge Interface auf br0
• Installation Headless
• IP anpassen in /etc/network/interfaces
  

  interfaces

  root@Net-Guard:~# cat /etc/network/interfaces
  # This file describes the network interfaces available on your system
  # and how to activate them. For more information, see interfaces(5).
  
  source /etc/network/interfaces.d/*
  
  # The loopback network interface
  auto lo
  iface lo inet loopback
  
  # The primary network interface
  allow-hotplug enp1s0
  #iface enp1s0 inet dhcp
  iface enp1s0 inet static
    address 192.168.30.8/24
    gateway 192.168.30.1
    dns-nameservers 8.8.8.8 8.8.4.4

• DNS temporär anpassen in nano /etc/resolv.conf
  

  resolv.conf

  root@Net-Guard:~# cat  /etc/resolv.conf
  # Generated by dhcpcd from enp1s0.dhcp
  # /etc/resolv.conf.head can replace this line
  domain fritz.box
  #nameserver 192.168.30.8
  # /etc/resolv.conf.tail can replace this line
  nameserver 8.8.8.8
