展示を参照してください。 エンジニアが NAT 変換を構成し、構成が正しいことを確認しました。 ソース IP はどの IP アドレスですか?
正解:D
NAT is used to send a packet to the outside network, using a public IP address to make it routable. The NAT logic is "inside-to-outside" FIRST and "outside-to-inside" THEN. This way, configuring NAT means "choosing a public IP address" for any outbound packet" IN THE FIRST PLACE, where "public IP address" translates to "inside global address". Among the given answers, the only inside global address is 172.123.104.4.
