Fresh Proxmox Iso Install --- Server Internet Not Working

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)
 
Hi,

can you ping 192.168.1.1 ?

Please post the network configuration as well.

for more information about network configuration you can follow this guide
 
Pinging 192.168.1.1 returns "Destination Host Unreachable"

Network Configuration:
Code:
auto lo

iface lo inet loopback

  netmask 255.255.255.0

  gateway 192.168.1.1

  bridge_ports enp0s31f6

cat /etc/hosts
Code:

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
 
I altered /etc/resolv.conf to include
Code:
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?
