<s>[INST] # Problem
An organization has two application servers, one is running on Linux and the other on Windows. Both servers have multiple network interfaces and each interface has multiple IP addresses assigned (using aliasing). The organization is concerned about data encryption and wants to ensure that only encrypted communication is allowed. On the Linux server, they are using iptables for firewalling, while on the Windows server, they are using Windows Defender Firewall. How would you resolve this problem and ensure only encrypted communication is allowed?[/INST]
