If A initiates a Web browsing session with D, and the E1 interface of the 208 is in NAT mode, what will be the source address of the packet arriving at host D? (Assume a single VR implementation)
A.
10.1.1.1
B.
10.1.10.5
C.
143.45.56.1
Explanation:
Interface-based source translation provides the ability to launch NAT off of a physical interface or a logical interface (e.g., a sub-interface).The interface with NAT mode enabled will perform NAPT by default for the ingress traffic.The source IP address used for translation will be the egress interface. In other words, whichever interface the packet exits from is the interface IP address that will be used as the translated source IP address. In this scenario the egress interface is E8 with ip address 143.45.56.1. Therefore the source address of the packet arriving at host D will be 143.45.56.1
