[SOLVED] No internet on Host but VMs and LXCs can be accessed

[xyz2610]

Hi,

This is the first time I've ever had a problem with my proxmox server that I could not solve myself. For some weird reason my Proxmox host loses internet access after a reboot. If I restart the networking service, the host often comes back online. But it would never survive a reboot.

My /etc/network/interfaces looks like this

auto lo
iface lo inet loopback

auto enp2s0
iface enp2s0 inet manual

auto vmbr0
iface vmbr0 inet static
    address  192.168.0.200
    netmask  255.255.255.0
    gateway  192.168.0.1
    bridge-ports enp2s0
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes
    bridge-vids 2-4094

Can anybody please help me?

I am running Proxmox 6.0-6

The only part of your config that looks suspicious to me are the last two lines for vmbr0:

    bridge-vlan-aware yes
    bridge-vids 2-4094

If you're using VLANs, this might be a source for your issue if not configured correctly.
If you don't use VLANs I would remove these two lines.

However, your post is already solved?
If so, can you explain how it was solved?

There was a dhcp ip route for enp2s0. I deleted that and disabled dhcpd on the host. Rebooted and voila the problem was fixed
