Using NAT makes troubleshooting difficult. You must know the IP address assigned to a device on its NIC and its translated address; it takes too long to determine the source and destination of an embedded IP address, and this delay is not appropriate for mission critical applications. Answer: B Explanation: Network Address Translation (NAT) simplifies and conserves IP address usage. NAT enables private IP internetworks that use nonregistered IP addresses to connect to the Internet. NAT operates on a router, usually connecting two networks together, and translates the private (not globally unique) address in the internal network into legal addresses before packets are forwarded onto another network.
What is the problem and what is the solution? A. IPsec encrypts Layer 4 port information and IKE NAT transversal needs to be configured on this network. B. The port number information in the ESP header is encrypted. Use ESP tunnel mode instead of transport mode. C. Router A needs to decrypt the Layer 4 port information. Configure ESP protocol on router A. com - The Power of Knowing 642-552 D. NAT changes the source IP address of the packets so IPSEC ESP integrity check will fail. Use PAT instead of NAT.
