The Firewall Management system allows you to create and configure network security rules to protect your virtual machines. Maximum limit: 25 firewalls per account.

Firewall Overview

The Firewall page displays your existing firewalls with detailed information (6 firewalls per page):

Firewall Information

Displayed Details

  • Firewall name and description
  • Status indicator (SUCCESS, CREATING, ERROR)
  • Region information
  • Creation date
  • Rule count
  • Attached VM count

Management Actions

Available Operations

  • View Details
  • Add Rule
  • Attach to VMs
  • Delete
  • Real-time status monitoring

Dashboard Statistics

The firewall management interface provides comprehensive statistics:

Firewall Metrics

System Overview

  • Total Firewalls: Number of firewalls in your account
  • Total Rules: Combined rules across all firewalls
  • Attachments: Total VM attachments across firewalls
  • Active Firewalls: Firewalls currently protecting VMs

Status Distribution

Operational Status

  • SUCCESS: Fully operational firewalls
  • CREATING: Firewalls being set up
  • ERROR: Firewalls with configuration issues
  • Regional Distribution: Firewalls by region

Creating Firewalls

To create a new firewall:

1

Access Creation

Click the “Create Firewall” button (disabled when limit reached)

2

Configure Basic Information

Enter firewall details:

  • Firewall name (required, maximum 50 characters)
  • Description (optional, maximum 255 characters)
  • Region selection from dropdown
3

Create Firewall

Click “Create Firewall” to initialize the new firewall

4

Configure Rules

After creation, add security rules to define traffic policies

Firewall Naming Requirements

Name Requirements:

  • Must be 1-50 characters
  • Supports letters, numbers, spaces, hyphens (-), underscores (_), and dots (.)
  • Must be unique within your account
  • No special characters or symbols allowed
  • Cannot be empty or contain only whitespace

Regional Considerations

Firewall Lifecycle

Creation Process

Before Creating Firewalls

  • Identify security requirements for your applications
  • Map network traffic patterns and dependencies
  • Determine required ports and protocols
  • Plan for different environments (dev, staging, prod)

Firewall States

Firewall is fully operational and ready to protect VMs

Firewall Limits and Quotas

Account Limitations

Firewall Limits

Quantity Restrictions

  • Maximum: 25 firewalls per account
  • Regional Distribution: No per-region limits
  • Rule Limits: Varies by firewall complexity
  • Attachment Limits: Multiple VMs per firewall

Resource Management

Efficient Usage

  • Plan firewall usage across projects
  • Reuse firewalls for similar applications
  • Delete unused firewalls to free quota
  • Group related rules in single firewalls

Best Practices for Limits

Firewall Information Display

Detailed Firewall Information

Each firewall displays comprehensive details:

Essential Details

  • Name: User-defined firewall identifier
  • Description: Optional purpose description
  • Region: Geographic deployment location
  • Status: Current operational state
  • Creation Date: When firewall was created

Security Rules Timing

Important Timing Information:

Security rules may take up to 10 minutes to be fully applied after creation. During this time, your VM may appear to have limited connectivity while the firewall configuration propagates across the network infrastructure.

Rule Application Process

1

Rule Creation

New rules are validated and saved to firewall configuration

2

Configuration Propagation

Rules are distributed to network infrastructure (up to 10 minutes)

3

Traffic Filtering

Rules become active and begin filtering network traffic

4

Monitoring and Validation

Test connectivity and validate rule effectiveness

Firewall Management Best Practices

Security Design Principles

Operational Best Practices

1

Planning and Design

  • Map application network requirements before creating rules
  • Design firewall architecture for scalability
  • Plan for different environments and use cases
  • Consider compliance and regulatory requirements
2

Implementation

  • Start with restrictive rules and open access gradually
  • Test rules in development environment first
  • Document all rules with clear descriptions
  • Implement changes during maintenance windows
3

Monitoring and Maintenance

  • Monitor firewall effectiveness and performance
  • Regular security audits and rule reviews
  • Update rules based on changing requirements
  • Remove obsolete or unused rules promptly
4

Incident Response

  • Plan for security incident response procedures
  • Maintain emergency access procedures
  • Document escalation and communication procedures
  • Regular disaster recovery testing

Firewall Integration

Integration with VM Workflow

VM Deployment

Deployment Integration

  • Attach firewalls during VM creation
  • Configure security rules before going live
  • Test connectivity after deployment
  • Monitor security effectiveness

Application Deployment

Application Integration

  • Configure rules for specific applications
  • Plan for application update requirements
  • Test application functionality with firewall rules
  • Monitor application performance impact

Automation and Scaling

Common Firewall Scenarios

Web Server Firewall

  • Purpose: Protect web servers and applications
  • Common Rules: HTTP (80), HTTPS (443), SSH (22)
  • Considerations: Load balancer integration, CDN compatibility
  • Monitoring: Web application performance and security metrics

Important Security Reminder:

Always test firewall configurations in a development environment before applying to production systems. Incorrect firewall rules can block legitimate traffic and impact application availability.

Use descriptive names and detailed descriptions for your firewalls to make management easier as your infrastructure grows. Consider creating template firewalls for common use cases that can be reused across projects.
