To enable GUI access to this launched instance, run following codes and then connect to the instance directly through your browser:

sudo apt install xfce4 xfce4-goodies tightvncserver xterm firefox -y
sudo update-alternatives --config x-terminal-emulator
snap install novnc
mkdir ~/.vnc
cat > ~/.vnc/xstartup <<EOF
#!/bin/bash
xrdb $HOME/.Xresources
startxfce4 &
EOF
chmod +x  ~/.vnc/xstartup

Using Pinggy Tunnel

Pinggy is the easiest way to get public URLs for your localhost. You can use it to quickly host a website from your laptop, receive webhooks, share files, connect to your Raspberry Pi, and more.

Follow the three simple steps to get started:

Step 1: Run your service in localhost

First you need to run the service you want to share in localhost. For example you may be using a webserver like Apache. Make sure your service is available in a localhost URL such as http://localhost:8080.

You can quickly launch such a server for testing purposes using Python: python3 -m http.server . This will start a server at http://localhost:8000.

Following screenshot is using port 80 for local http site. 

Step 2: Create a tunnel using a single command

ssh -p 443 -R0:localhost:80 a.pinggy.io

Replace the port 80 with the localhost port where your service is running.

Step 3: Access through public URL

The above command will provide you http and https URLs as follows:

You can access local server via following URL(s):
http://fakqxzqrohxxx.a.pinggy.online
https://fakqxzqrohxxx.a.pinggy.online

You can access your localhost service using these URLs.

Scanning Outgoing Ports to Find out Non-Restricted Ports

Mapping all the open outgoing ports is actually pretty straightforward, with two tools: nmap and portquiz.

Install nmap:

• apt install nmap
• snap install nmap
• You have to grant network access to nmap with: snap connect nmap:network-control

Finding restricted ports is as easy as scanning all the ports of Portquiz or scanme.nmap.org with nmap:
