Proxmox LXC unable to access the internet

Hi

I just started my proxmox node with the intention of playing around with steamcmd.
I was following this guide
https://developer.valvesoftware.com/wiki/SteamCMD#Linux
The LXC in question is based on the Ubuntu 20.04.

The issue I am having is that the LXC do not have access to DNS nor the internet so I cannot get the apt installation to work. The host has internet access and DNS.

Here are my network settings for the host


And the settings for the LXC

Edit: Added DNS

Any ideas to get that DNS and internet access to work properly?

Thank you already in advance!
