**🌟 Task 13 - Configure Firewall to Restrict Apache Port 8088 Access**
**📌 Task Description**
Due to security concerns, the **xFusionCorp Industries** team has decided to add a security layer by configuring **iptables firewalls** on all app servers in **Stratos Datacenter**.
**Requirements:**
1. Install **iptables** and all dependencies on all app servers
2. Block incoming traffic on **port 8088** (Apache port) on all app servers except from the **LBR host** (172.16.238.14)
3. Ensure the firewall rules **persist after system reboot**
👉 **Your task:** Configure selective port access using iptables to allow only the load balancer to reach Apache on port 8088.
💡 **Note:** Perform these steps on **all app servers**: stapp01, stapp02, stapp03.
