[ ] Explore How VPNs Work:
Understand tunneling protocols like OpenVPN, L2TP, and PPTP.
Discuss advantages and disadvantages of each protocol.
[ ] VPN Setup and Configuration:
Set up a basic VPN connection using a chosen protocol.
Document the process and highlight key configuration settings.
Step 3: Advanced Concepts and Integration (1 week)
[ ] Analyze VPN Traffic:
Capture VPN traffic using Wireshark and analyze the encapsulation of data packets.
Explore the encryption mechanisms involved in VPN communication.
[ ] Evaluate the Role of Network Protocols in VPNs:
Determine how TCP/UDP are utilized in VPN software.
Address the impact of HTTPS over VPN connections.
Step 4: Practical Application & Blog Post (1 week)
[ ] Application Testing:
Test a popular VPN software, analyzing its usage of protocols.
Maintain a log of your findings and insights observed.
[ ] Summarize Learnings in a Blog Post:
Compose an article articulating the function and application of network protocols in VPNs.
Include screenshots and technical descriptions from your practical tests.
