Hi there! I am doing a unit called Virtual Private Networks. My lecturer has given me a scenario which has a diagram as well. and the diagram is showing the connections between different servers. Just wondering if I can the answers of some questions from the scenario. Below I will provide the discription and the diagram along with the questions. Thanks.

Scenario: STARNET is a company that has two sites (Site A and Site B) that are located in Melbourne and Sydney, needs to communicate between the two sites and exchange the data securely. As indicated in the figure below, the corporate servers and other resources are shared in both sites. Virtual Private Network (VPN) can be a potential solution to access resources from corporate desktops at both sites to the other sites corporate servers.

As there are number of ways or VPN types to connect the two sites such as IPsec, etc., you are required to choose a suitable type of VPN to implement in this scenario.

Propose and justify VPN implementation plan to connect Site A and Site B together. The implementation plan must ensure that local area networks at both sites are accessible to each other.

Assume suitable IP addresses for both sites (both LANs) and for the WAN connection between routers R1 and R2.

The report should address the following:

1. A table showing all the interfaces at every site (Internal private IP interface and external public IP interface).

2. What type of VPN is chosen to implement? And why you have chosen this type of VPN?

3. Explain the difference between Site to Site and Remote Access VPN, and how can we benefit from both in our scenario.

4. What are the security features it can provide to protect data?

5. In case of using IPSec, What are the 3 protocols used in that case? Explain your answer.

6. Explain in details the advantages and disadvantages brought by the VPN to the network.

Thats all. I will be really grateful if someone can help me out. Thanks
