Hello everyone, I'm a newcomer to Proxmox and I'm excited to share my experience with you. I've been using an OrangePi 5 as part of my journey to build a home lab, and many tutorials I've followed have recommended using Proxmox for its ease of use and flexibility.


Recently, I installed the Armbian system on my OrangePi 5 and then went ahead to install Proxmox. After setting up the network bridge, I was able to access Proxmox's web interface without any issues. However, I'm having trouble establishing a connection to the outside world - in other words, I don't have internet access.


I've tried various troubleshooting steps, but nothing seems to be working for me. Has anyone else encountered this issue or know of a solution? Any help or guidance would be greatly appreciated.
 
Bash:
auto lo
iface lo inet loopback

iface end1 inet manual

auto vmbr0
iface vmbr0 inet static
        address xxx.xxx.x.77/24
        gateway xxx.xxx.x.1
        bridge-ports end1
        bridge-stp off
        bridge-fd 0

        post-up   echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up   iptables -t nat -A POSTROUTING -s '10.10.10.0/24' -o eno1 -j MASQUERADE
        post-down iptables -t nat -D POSTROUTING -s '10.10.10.0/24' -o eno1 -j MASQUERADE
 
OrangePi 5 is not x86 Hardware, so there is not support over this forum and the proxmox gmbh.
It will not work, as you expected.
