PVE 6.2 2xPublic IPv4 Configuration + NAT, Guest

[ChuckNorris99]

Hello together,

I'm running 1 lxc and 1 vm at the moment and I got some strange Network Problems.
I run a webserver on my ubuntu 18.04 lxc and i can acces is normally, but i can't e.g. run "apt update" in it
I want 1 IPv4 only for the VM and the other IPv4 for multiple LXC Containers with NAT

Here the configuration from my system:

Interfaces:


IP A:

IP LINK:


LXC Container Network config:


iptables:



Any Idea what I am doing wrong?( probabbly everything ).

Many thanks in advance for your answers.

bridge vmbr0 to eth0 like bridge_ports eth0

bridge vmbr0 to eth0 like bridge_ports eth0

Now i cant reach anything

I had a config before whrere i had vmbr1 bridged to eth0, this wasn't working too. (I always had to restart networking then sometimes it worked, but this time this fix is not working)

EDIT: I also cant ping out from proxmox

Firewall is deactivated for testing.

I already got the NAT config 3.3.6 working. But without the second IP it does not help me. I didnt see any configuration with 2 IP's and NAT on this Site.
