I need help with the Network Configuration

[Gliksamar]

I’m trying to install Proxmox on a Beelink mini s12 Pro.
I have a simple network with a FiberHome router from the internet provider, which is really bad and slow in the settings.
I set up DHCP Static Leases (DHCP MAC Binding List because it’s the only thing remotely close to static IP in those settings) for its MAC to 192.168.1.123, installed it with that address. It boots into the login screen, shows me the address but it doesn’t connect to the network. On the router’s admin page I don’t see it connected at all. I see it connected only in the installation process.

I successfully installed Proxmox before on an old laptop, and it worked but I don’t exactly remember how I did it, and it was in a different location with a TP Link router.
I have no idea what I should write in the Management Network Configuration page, but I would like to configure it only once and when I will go to the other location just change in the router the MAC address of the old laptop with the one of the Beelink.
I didn’t find any YouTube tutorial helpful… Please help.

Did you open a browser (eq. Firefox, Chrome, etc.) and enter https://192.168.1.123:8006/ in the address bar and press enter?

Yes. Tried even searching the hostname (.local) and pressing enter. But since it doesn't connect to the network there is no chance finding something. Will it be easier setting up with a private DNS?

Login directly on the local console and execute:

ip -c a

May be there are some naming error or network driver isn't loaded.

it's like AP isolation enabled on your router which prevent traffic from wireless devices to other devices,or firewall rules.
try over the wire.

please, post large code into "code" instead "inline code"

I remember something like this happen to me.

[Gliksamar]

can I bypass this situation by configuring it to a public DNS?

 

[proxstormer]

DNS is not involved in your problem, your are using ips.

mmm, I think you want to connect PVE on the LAN side, then you don't need to assign to the router the MAC of your PVE server, the only thing you be careful is to have an IP out of your LAN dhcp range.

Also be careful to connect to a port of your router that is a LAN port, some routers have special ports with vlans for the media player, can you change the port that is attached to your server?.

All seems to indicate that your server and your notebook aren't on the same network.

If you have a switch can you can connect both via cable and test it again?

What does it mean out of its range? I have this in router:

Start IP​	192.168.1.2
DHCP End IP​	192.168.1.254

Does it need to be anything but that interval? Like 200.200.200.200
I don't have many devices so that my .123 would never have been reached.
And where do I need to put that ip if not assinging it to its MAC? Can Proxmox choose what ip it wants to have when it connects to the router?

some routers have special ports with vlans

They are all the same, and it's the same cable I use when I want faster speeds for my laptop or TV. But I just changed ports anyway.
Same problem.

I'm installing it again, this time without Binding a MAC to ip. Please let me know if I'm doing it wrong.
