host and guest not visible in local network

[tredok]

Hello,

I've got a new modem-router (Zyxel VMG8825-T50) and I've got an issue with Proxmox (7.4-17). My problem seems linked to Proxmox.

At first, my host dosen't appear on my local network. I fact, it appear four or five times, but disappear. I can't reach the GUI. But, I can access to it via SSH, Webdav, or mounting a samba share. The VM are not detected and I can't reach any of them.

This morning, I've tried to list the VM, and Proxmox send me an error which help to solved some things. I've added the host name in /etc/host. Now, :
* connect to GUI : ok
* guests detected : ok

There are still two problems :
* host is not detected in my local network, but I can ping google and updated the OS
* guests doesn't have access to the web

Do you have an idea ? Is there some things I can do to investigate ?

Hi,

Hard to say without more inforamtion, could you please share your network configuration and the output of `ip a` command from your Proxmox VE host?

What do you mean about the network configuration ? The architecture, which hardware ? A schema ? Or some files ?

The output of ip a

What do you mean about the network configuration ?

The network config of your Proxmox VE `cat /etc/network/interfaces`

 

[tredok]

There it is :

auto lo
iface lo inet loopback

auto enp2s0
iface enp2s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.253/24
        gateway 192.168.1.254
        bridge-ports enp2s0
        bridge-stp off
        bridge-fd 0

Update.

Guest have access to internet. A service was down.

Host is still not detected. It works but I'm not sure it's normal. If you think it is, then my problem is solved ^^
