Answer #1

1. STUN: STUN stands for Session Traversal Utilities for NAT. The peer address problem in NAT can be solved using STUN. With this technique, media packets can be sent to these addresses and mapping can be done in NAT. With this technique, the client and sender can communicate with each other easily.

2. TURN: TURN stands for Traversal Using Relays around NAT.In this technique media relay being used for transmission. It is costly since it requires more bandwidth and latency time.

    Network Address Traversal (NAT) allows multiple LAN machines with private IP addresses to communicate with Internet based servers using one public IP addresses. Virtual Private Network (VPN) allows external access to internal LAN resources by creating a secure 'tunnel' between the remote machine and the firewall. Both of these techniques are widely used in corporate networking today, yet both involve inherit risks. Can you think of some ways that configuring these protocols could pose a security risk? Respond with your...

    (1) Computer hosts usually have two addresses, an Internet Protocol (IP) address and an Ethernet Media Access Control (MAC) address. For the benefit of humans, the IP address is normally represented as a dotted decimal notation, such as 192.168.10.2. Each of the decimal octets in the address or a mask can be converted to 8 binary bits. Remember that the computer only understands binary bits. If all 4 octets were converted to binary, how many bits would there be? (2)...
