Problem: No Internet access on my first vm
*** Host ***
I started with a raspberry pi5 with 8GB with a NVME pcie SSD.
Installed bookworm lite OS on SSD with UEFI boot using USB ethernet adapter port (eth1).
I setup a bridge using nmcli/nmtui on rpi5 and got Internet access (refer to attached config)
Installed Proxmox v8.3 for arm64 on NVMe SSD successfully
Note: I would prefer to use network-manager over netplan because I am more familiar with nmcli even thought it is ubuntu server.
After I get Internet access I will eventually install a desktop on top of ubuntu server. I cannot install nmcli because I have no Internet access on vm.
*** Guest ***
Attempting to install Ubuntu server 24.04 LTS as my first VM.
This is where the problem starts.
I cannot get Internet access after setting up a bridge using netplan config file named 01-netcfg.yaml (refer to attached config file).
I am struggling with YAML syntax and getting Internet access via a simple bridge.
Applied netpan -01-netcfg.yaml (refer to attached config file) however when I ping google.com I get an error message "temporary failure in name resolution error"?
I have defined the nameserver, route and bridge in 01-netcfg.yaml.
I don't understand why I cannot access the Internet??
Noticed on my pfsense router I am getting arp errors "arp: 1e:a5:6e:39:13:ff attempts to modify permanent entry for 10.0.1.12 on igc0" (refer to attached pfsense log file).
Now I cannot launch proxmox probably due to the arp errors.
Cannot access rpi5 via ssh and get "connection refused probably due to the arp errors.
After a few minutes I can launch proxmox and ssh into rpi5 however I cannot access the Internet on ubuntu vm.
This keeps repeating?
I know that I screwed things up probably by attempting to install a bridge on both the host and guest?
I assumed both the host (rpi5/proxmox) and guest vm (ubuntu server) have to have a bridge setup?
Please note I am new to rpi5, linux and proxmox so bear with me I am only trying to learn.
