Firewall Simulator

This is a simple Python-based firewall simulator that randomly generates IP addresses within the 192.168.1.0/24 range and checks whether they are allowed or blocked based on predefined firewall rules.

Features

• Generates random IP addresses dynamically.

• Uses predefined firewall rules to allow or block specific IPs.

• Displays the result with color-coded output (red for blocked, green for allowed).

• Assigns a random process ID for each IP request.

Requirements

Ensure you have Python installed along with the required dependencies:

pip install colorama termcolor

Usage

Run the script using:

python firewall_simulator.py

How It Works

1. The script generates 20 random IP addresses in the 192.168.1.0/24 subnet.

2. It checks each IP against the predefined firewall rules.

3. If the IP is in the blocklist, it prints the result in red.

4. If the IP is not in the blocklist, it prints the result in green.

5. A random process ID is assigned for each request.

Firewall Rules

The firewall currently blocks the following IPs:

192.168.1.3
192.168.1.5
192.168.1.9
192.168.1.12
192.168.1.14
192.168.1.18
192.168.1.23
192.168.1.35

Any other IPs are allowed by default.

Example Output

IP: 192.168.1.7, Action: Allow, ProcessID: 3452  (Green)
IP: 192.168.1.5, Action: Block, ProcessID: 8723  (Red)
