A network engineer is asked to configure a "site-to-site" Ipsec VPN tunnel. One of the last things that the engineer does is to configure an access list (access-list 1 permit any) along with the command ip nat inside source list 1 int s0/0 overload. Which functions do the two commands serve in this scenario?

• A.The command access-list 1 defines interesting traffic that is allowed through the tunnel.
• B.The command ip nat inside source list 1 int s0/0 overload disables "many-to-one" access for all devices on a defined segment to share a single IP address upon exiting the external interface.
• C.The command access-list 1 permit any defines only one machine that is allowed through the tunnel.
• D.The command ip nat inside source list 1 int s0/0 overload provides "many-to-one" access for all devices on a defined segment to share a single IP address upon exiting the external interface.

Correct Answer: D

Configuring NAT to Allow Internal Users to Access the Internet Using Overloading

Note in the previous second configuration, the NAT pool "ovrld"only has a range of one address. The keyword overload used in the ip nat inside source list 7 pool ovrld overload command allows NAT to translate multiple inside devices to the single address in the pool.
