Container's have no internet connection

From PVE host what is the output of:
# dig debian.org

and

# cat /etc/network/interfaces

- you do not have to mask the ip addresses, unless they are public addresses.
 
PVE Host i cant offer right now as i bricked the internet connection again so im reinstalling proxmox for the 10th or so time now and heres network interfaces: https://i.imgur.com/aFI03N6.png

masked because its public ips
my goal (if it helps) is to be able to create containers on the go for my friends / other to ssh into and run stuff inside or so (and also to be able to assign multiple ports for them so eg they ssh in with port 622 but can also expose stuff to the "outside" on port 623 but not any other port
 
Late but heres #dig debian.org https://i.imgur.com/T2sPPCc.png

yes its running from a datacenter to be more specific its a Dedicated Server hosted by hetzner
i only have 1 IP available btw wanna get it working with only 1 as ik its possible
 
quote from the link I gave you earlier :

Proxmox VE server at hosting provider, with a single public IP address​

In that case the only way to get outgoing network accesses for your guest systems is to use Masquerading. For incoming network access to your guests, you will need to configure Port Forwarding.
