Hello everyone,

I just bought a Server at Hetzner and tried to setup the additional subnet that they gave me. I'm getting the strange problem whenever I try to bridge one of my subnet IP's to a LXC Container, the main proxmox Server responds instead (pve-manager/4.4-18/ef2610e8 (running kernel: 4.4.83-1-pve).

Here is my interfaces config:

Code:
auto lo
iface lo inet loopback
iface lo inet6 loopback

auto eth0
iface eth0 inet static
  address 1.2.3.4
  netmask 255.255.255.255
  gateway <Gateway IP>
  pointopoint <Gateway IP>


auto vmbr0
iface vmbr0 inet static
  address 120.120.120.120
  netmask 255.255.255.240
  bridge_ports none
  bridge_stp off
  bridge_fd 0


iface eth0 inet6 static
  address ...
  netmask 64
  gateway ...

If I use the vmbr0 bridge on my Container, the Container wont respond, instead proxmox itself answers.

Since I'm fairly new and many tutorials out there tell a different story, I'm stuck with the problem.

Best Regards
 
//edit: Ok IP Forwarding wasnt enabled after reboot, now the Container is still not reachable but proxmox itself wont respond to the IP anymore.
 
yes, I ended up with the

Code:
up ip route add <2nd additional IP>/32 dev vmbr0
method for every ip, isnt the nicest way though.
