    Strange issue: my VMs are up and running, I can ping them, but all packets are lost when pinging the host ip and GUI web interface is down.

    Event:
    Issue occurred when I attempted to change routers. I think I assumed the proxmox host would get a new ip address along with its VMs and my other devices and I would pick up where I left off. That didn't happen so I made a few attempts to force it onto the new subnet, failed, and put everything back the way it was on the old router... but proxmox web interface is now down

    Background Info:
    I have 3 NICs on the machine. currently only one is in use

    /etc/network/interfaces looks normal compared with others (attached) note that eth0 has been renamed to eno1, eth1 and eth2 have also been renamed.

    /etc/hosts has the same ip as in my routers dhcp address table

    I'm connected to the host with keyboard and monitor
    ping gateway_ip
    ping 8.8.8.8
    ping pc_ip
    all result in: "connect: Network is unreachable"

    /etc/udev/rules.d/70-persistent-net.rules is empty
    ifconfig results in "command not found", so I don't have that
    pveversion is 5.1-41/0b958203

    This is a home use case, VMs are plex, home automation, NAS4Free, and soon to be pfsense

    Hi,

    Your network config has no IP address setting for them host.
    So there is no IP where you can connect to.

    Thank you,

    I've set the config to "static" /etc/network/interfaces and defined an ip. Required a restart but I got it working

    ...
    iface eno1 intet static
    ip 192.168.1.2
    gateway 192.168.1.1
    netmask 255.255.255.0
    ...
