The NAT keeps a table mapping the Internet and ports to private address and
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...
