Question

You have a small network connected to the Internet as shown in the Exhibit. Both Srv1 and Srv2 need to be contacted by Internet hosts. Which of the following tasks are required parts of the solution?

1) Configure port forwarding on the router
2) Install a firewall on Srv1 and Srv2
3) Configure a static IP address on Srv1 and Srv2
4) Enable NAT on the router

Answer 1

The student's network requires configuring port forwarding, setting static IP addresses on the servers, and enabling NAT on the router. Installing firewalls on the servers is recommended for security, although not directly related to connectivity.

Step-by-step explanation:

The question pertains to the necessary configurations for allowing Internet hosts to contact servers (Srv1 and Srv2) in a small network. To accomplish this, certain tasks must be considered as part of the solution:

1. Configure port forwarding on the router to direct incoming Internet traffic to the appropriate server on the network.
2. While not necessarily required for connectivity, it's highly recommended to install a firewall on Srv1 and Srv2 for security purposes.
3. Configure a static IP address on Srv1 and Srv2 to ensure that the servers have a fixed address within the local network, which simplifies port forwarding and network management.
4. Enable NAT (Network Address Translation) on the router to allow multiple devices on the local network to share a single IP address provided by the ISP, which is also essential for Internet connectivity.

These actions will ensure that the servers can be reached from the Internet while maintaining network security and stability.
