Task 1: Introduction to Port Forwarding

What is the name of the device that is used to configure port forwarding?

The answer is listed at the very bottom. "Port forwarding is configured at the ______ of a network."

Task 2: Firewalls 101

What layers of the OSI model do firewalls operate at?

For this answer, just provide the numbers in ascending order, separated by an ampersand (&) I.e: 4 & 5

Based on my knowledge of the **OSI** model from other rooms (Network and Transport Layers), I came to the conclusion the firewalls operate at *_ & _*

What category of firewall inspects the entire connection?

"If a connection from a host is bad, it will block the entire device." This helped me conclude it was ________.

What category of firewall inspects individual packets?

This one is exactly the opposite of the previous. "This firewall type uses a static set of rules to determine whether or not individual packets are acceptable or not" this helped me decide it was _________.

Task 3: Practical - Firewall

What is the flag?

To find the flag I did the practical simulation and blocked the packets from reaching the server so it wouldnt overload. The flag was **THM**{________}

Task 4: VPN Basics

What VPN technology only encrypts & provides the authentication of data?

When looking through the different types of vpn tech, I see "This technology is not capable of leaving a network by itself (non-routable)." This is why I went with ___

"Switches can operate at both layer 2 and layer 3 of the **OSI** model. However, these are exclusive in the sense that Layer 2 switches cannot operate at layer 3." this is how I came to my conclusion _____ _, _____ _.

Task 6: Practical - Network Simulator

What is the flag from the network simulator?

What I did was send a tcp packet from computer 1 to computer 3. That's how I got **THM**{insert_flag_here}

How many HANDSHAKE entries are there in the Network Log?

I counted the handshake logs after I received my flag and that's how I got _.
