    post-up iptables -A FORWARD -i vnet1 -j ACCEPT
    post-up iptables -A FORWARD -o vnet1 -j ACCEPT

Code: 
root@pve:~# cat /etc/network.d
cat: cannot access '/etc/network.d': No such file or directory

I have network and networks in /etc though.

Code: 
root@pve:~# iptables -L -t nat

Thanks - traceroute to another host gives:

Code: 
user@debian:~$ traceroute 192.168.50.246
traceroute to 192.168.50.246 (192.168.50.246), 30 hops max, 60 byte packets
1 debian (169.254.11.14) 3077.298 ms !H 3077.283 ms !H 3077.278 ms !H

vnet1 is 192.168.52.1, pinging just hangs (no message, blinking cursor):

Code: 
user@debian:~$ ping 192.168.52.1
PING 192.168.52.1 (192.168.52.1) 56(84) bytes of data.

Router gateway 192.168.50.1 is unreachable:

Code: 
user@debian:~$ ping 192.168.50.1
PING 192.168.50.1 (192.168.50.1) 56(84) bytes of data.
From 169.254.11.14 icmp_seq=1 Destination Host Unreachable
From 169.254.11.14 icmp_seq=2 Destination Host Unreachable
From 169.254.11.14 icmp_seq=3 Destination Host Unreachable

Ping is failing from the VM to the vnet1 interface 192.168.52.1. Check your VM Hardware configuration. Check the Network Device and ensure it is bridged to vnet1. My guess is the Network Device is bridged to vmbr0, which is a network blackhole.
