Integration with Configuration Management

Modern infrastructure often uses configuration management tools to ensure consistency across multiple servers. Both iptables and UFW can be managed through popular tools like Ansible, Puppet, or Chef.

Ansible example for UFW management: ```yaml

name: Configure UFW for web servers hosts: webservers become: yes tasks:
- name: Set default policies ufw: direction: "{{ item.direction }}" policy: "{{ item.policy }}" loop:
  - { direction: incoming, policy: deny }
  - { direction: outgoing, policy: allow }
- name: Allow SSH from admin network ufw: rule: allow port: '22' proto: tcp src: 10.0.0.0/24
- name: Allow web traffic ufw: rule: allow port: "{{ item }}" proto: tcp loop:
  - '80'
  - '443'
- name: Enable UFW ufw: state: enabled


Managing iptables with configuration management requires careful orchestration to prevent lockouts and ensure atomic updates. Always test configuration management playbooks in staging environments before applying to production servers.

Linux firewalls provide powerful and flexible protection for web servers. Whether using iptables for fine-grained control or UFW for simplified management, understanding the underlying concepts and best practices ensures effective security configuration. Regular review, testing, and updates keep your firewall rules aligned with evolving security requirements and threat landscapes.## Windows Server Firewall Configuration Step by Step
