Windows Firewall

A Rust crate for managing Windows Firewall rules and settings using the Windows API in Rust.

Features

• Create, modify, and delete firewall rules
• Check firewall status and active profiles
• Manage incoming and outgoing rules
• Full control over rule properties:
  • Ports and protocols
  • Applications and services
  • Network interfaces
  • IP addresses
  • ICMP settings
  • Edge traversal
  • Security profiles

Installation

Add this to your Cargo.toml:

[target.'cfg(windows)'.dependencies]
windows_firewall = "0.1.0"

Usage Examples

Creating and Managing Rules

use windows_firewall::{
    add_rule, remove_rule, rule_exists, update_rule, WindowsFirewallRule, WindowsFirewallRuleSettings,
    ActionFirewallWindows, DirectionFirewallWindows, ProtocolFirewallWindows
};

// Create a new rule
let mut rule = WindowsFirewallRule::builder()
    .name("TestHTTPRule")
    .action(ActionFirewallWindows::Allow)
    .direction(DirectionFirewallWindows::In)
    .enabled(true)
    .description("Test HTTP rule")
    .protocol(ProtocolFirewallWindows::Tcp)
    .local_ports([80])
    .build();

// Add the rule
match add_rule(&rule) {
    Ok(_) => println!("Rule added successfully"),
    Err(e) => eprintln!("Failed to add rule: {}", e),
};

// Verify the rule exists
match rule_exists("TestHTTPRule") {
    Ok(exists) => println!("Rule exists: {}", exists),
    Err(e) => eprintln!("Failed to check rule: {}", e),
};

let updated_settings = WindowsFirewallRuleSettings::builder()
    .enabled(false)
    .description("Updated test HTTP rule")
    .build();

// Update the rule
match update_rule("TestHTTPRule", &updated_settings) {
    Ok(_) => println!("Rule updated successfully"),
    Err(e) => eprintln!("Failed to update rule: {}", e),
};

// Remove the rule
match remove_rule("TestHTTPRule") {
    Ok(_) => println!("Rule removed successfully"),
    Err(e) => eprintln!("Failed to remove rule: {}", e),
};

Another example of using struct methods

use windows_firewall::{
    WindowsFirewallRule, WindowsFirewallRuleSettings,
    ActionFirewallWindows, DirectionFirewallWindows, ProtocolFirewallWindows
};

// Create a new firewall rule
let mut rule = WindowsFirewallRule::builder()
    .name("TestDNSServerRule")
    .action(ActionFirewallWindows::Allow)
    .direction(DirectionFirewallWindows::In)
    .enabled(true)
    .description("Test DNS Server rule")
    .protocol(ProtocolFirewallWindows::Udp)
    .local_ports([53])
    .build();

// Add the rule
match rule.add() {
    Ok(_) => println!("DNS Server rule added successfully"),
    Err(e) => eprintln!("Failed to add DNS Server rule: {}", e),
};

// Verify the rule exists
match rule.exists() {
    Ok(exists) => println!("Rule exists: {}", exists),
    Err(e) => eprintln!("Failed to check rule: {}", e),
};

let updated_settings = WindowsFirewallRuleSettings::builder()
    .enabled(false)
    .description("Updated DNS Server rule")
    .build();

// Update the rule
match rule.update(&updated_settings) {
    Ok(_) => println!("DNS Server rule updated successfully"),
    Err(e) => eprintln!("Failed to update DNS Server rule: {}", e),
};

// Remove the rule
match rule.remove() {
    Ok(_) => println!("DNS Server rule removed successfully"),
    Err(e) => eprintln!("Failed to remove DNS Server rule: {}", e),
};

Checking Firewall Status

use windows_firewall::{get_firewall_state, ProfileFirewallWindows};

match get_firewall_state(ProfileFirewallWindows::Public) {
    Ok(enabled) => println!("Firewall is {}", if enabled { "enabled" } else { "disabled" }),
    Err(e) => eprintln!("Failed to get firewall state: {}", e),
}

Listing Firewall Rules

use windows_firewall::list_rules;

match list_rules() {
    Ok(rules) => {
        for rule in rules {
            println!("Rule: {}", rule.name());
            println!("  Direction: {:?}", rule.direction());
            println!("  Action: {:?}", rule.action());
            println!("  Enabled: {}", rule.enabled());
        }
    },
    Err(e) => eprintln!("Failed to list rules: {}", e),
}
