Refer to the exhibit. R1 is performing NAT overload for the 10.1.1.0/24 inside network. Host A has sent a packet to the web server. What is the destination IP address of the return packet from the web server?

A
172.30.20.1:3333
💡 Explanation:
With NAT overload (PAT), the router translates both the source IP and source port of internal traffic. The web server receives the packet with source IP 172.30.20.1 and source port 3333, so it sends the return packet to that same destination IP and port. The NAT table then translates it back to 10.1.1.2:1234.
