Hello Tamil Selvan M,

Welcome to microsoft Q&A, Thankyou for posting your query here.

• Windows servers often come with Windows Firewall settings that automatically let data out. This setup means they don't need any special adjustments to start browsing the web.
• Essentially, these servers have the green light to start conversations with the internet, bypassing the need to manually set permissions for those outbound chats.
• When we talk about reaching out to the internet, it's the outbound traffic that really matters, not so much the incoming one.
• Looking at ports 80 and 443, it's not about the server reaching out but rather letting the outside world in, specifically for web hosting purposes.
• Flexibility is key with both Windows and Linux systems; they can adapt their security measures to fit what's needed, be it tightening up for more protection or loosening up a bit.
• If you're on Linux and bumping into connection roadblocks, a good first step is to peek at your firewall rules.
