Host unreachable after fresh installation of PROXMOX VE 8.2

[kittaneh]

Hello,

I am trying to install PROXMOX VE 8.2 for the first time. After fresh installation I couldn't reach the PROXMOX from any device. and it is not visible on my local network. I am attaching the results of the /etc/network/interfaces and the result of ip -a command.

Thanks,

There should not be a netmask 255.255.255.0 because the IP address already ends with a /24. I assume the gateway is indeed your local router's IP address? Make sure the Proxmox IP address is not inside the DHCP range of the router (or make sure it is reserved) as Proxmox does not support DHCP out of the box (except that the installer uses DHCP once).

Also, since you don't specifically mention, can you ping the proxmox-server, or from the proxmox-server can you ping the router or your PC?
And how did you get these logs btw, did you type them all over, or otherwise?

Yes, I did ping, always got Host Unreachable. Regarding submitting the files, I redirected the output of the commands to files using the operator > and cp to a usb flash

The netmask probably just gets ignored (it's deprecated and you have correctly /24), the ip a looks fine.

Yes, I did ping, always got Host Unreachable.

My gut feeling would be ...

Make sure the Proxmox IP address is not inside the DHCP range of the router (or make sure it is reserved) as Proxmox does not support DHCP out of the box (except that the installer uses DHCP once).

So are you absolutely sure there's nothing else on that address, or can you check?
