Dear all,
EDIT: RESOLVED FINALLY !!!
I changed the 'vmbr0' to 'eno1' in the NAT configuration. Worked after rebooting the node. Now VM has internet access.
I have a requirement to setup multiple VMs in different isolated networks. Also, these VMs should be able to have internet access. So far I have done the following. I am trying to fix the internet issue. I am running ubuntu server 22.04.4 LTS (Jammy Jellyfish). Proxmox host have internet access.
		
		
	
	
		 
	
Added the vmbr1 as the network bridge to the VM
		 
	
IP details of the VM which is connected to vmbr1
		 
	
/etc/netplan config file
		 
	
However, when I run netplan apply i get the below error. But, when I click enter it accept the changes
		 
	
I am not sure why still the VM cannot access internet.
I followed the below resource
		 
	
The only difference is here the eno1 is configured with a public IP and vmbr0 is with a private IP. In my case, vmbr0 was automatically setup in installation. So I created vmbr1 as a new bridge and applied the settings accordingly.
		 
	
Finally iptables-save output is as below. Taken from proxmox node (host)
		 
	
Any help would be greatly appreciated. I am trying to figure out the issue. Thank you!

- created new bridge (vmbr1) for NAT and assigned IP 192.168.100.1/24.
- Edited the /etc/network/interfaces file in the proxmox server (host).
