I have, not much, prior experience with networking and linux and no prior experience with proxmox.
During set up of my ubuntu guest I was able to update fine no issues, indicating that I had access to the internet.
After that I have not been able to access the internet, I do have a LAN ip and I can ssh into the guest, I can ping it, no problem.
I have tried searching the forum but came to no concrete fix.
What am I missing and how do I fix this?
I can ping my gateway as well
In the guest, I have changed some things to get a static IP but I doubt this is the reason as I had the same issue on another system which I installed proxmox on first.
I disabled the cloud-init thingy by adding config:disable to a network cfg, it is now disabled.
I added this because I still got a DHCP address
I deleted the config file that enabled dhcp in netplan, filename started with `50-`
I don't know if vmbr0 should be visible from the guest, but at least the network device is visible.
interfaces does not exist in the guest..
