Fresh Proxmox Iso Install --- Server Internet Not Working

[John Deere]

I wish to run Proxmox in a desktop style configuration and am following this guide: Dev Workstations with Proxmox and X11

After installing the .iso and rebooting the pc I am able to login and configure settings. I desire to run "apt-get update && apt-get dist-upgrade" to install X11 and achieve the desktop setup but networking does not work. I can't access the server in a browser on the local network and I can't "ping www.google.com" from the actual server.

1. As I wish for a desktop style configuration is it possible to disable the Proxmox server and have it utilize localhost instead so local PC's can't access it whatsoever (Only want to use Proxmox for the host machine).
2. I am a n00b in terms of networking so I am certain the networking issue is my fault. I am confused on what to put for the FQDN if I want it to only work locally. I don't understand why I would need to setup a DMZ or port forward if I want the server to work locally.
Wiki Example of GUI Networking Setup
My GUI Networking Setup on fresh install:
Hostname: proxmox.example.com
IP: 192.168.1.222 (My router has a range of addresses between 192.168.1.[10-254]. Do I need to set a static address on my router?)
Netmask: 255.255.255.0 (Found in router configuration)
Gateway: 192.168.1.1 (Router Address)
DNS Server: 8.8.8.8 (Google DNS)

Should I change the hostname to 127.0.0.1 instead?

 

[Moayad]

hi,

search aurel1us.net

please post output of cat /etc/hosts

 

[John Deere]

cat /etc/hosts

127.0.0.1 localhost.localdomain localhost
192.168.1.222 milan.aurel1us.net milan

# The following lines are desirable for IPv6 capable hosts

::1            ip6-localhost    ip6-loopback
fe00::0        ip6-localnet
ff00::0        ip6-mcastprefix
ff02::1        ip6-allnodes
ff02::2        ip6-allrouters
ff02::3        ip6-allhosts

try to make your resolv.conf like:

search milan
nameserver 192.168.1.1

 

[John Deere]

I altered /etc/resolv.conf to include

search milan
nameserver 192.168.1.1

restarted the server and tried running ping again. It didn't work.

Is there a default networking configuration that I can copy so the PC acts as a workstation?

Is there a default networking configuration that I can copy so the PC acts as a workstation?

You can with dhclient -d command, if now work you can try nslookup aurel1us.net and host aurel1us.net

hope that helps
