In the figure below, Localnet is an internal network with private addresses A corresponding set of
public addresses is available as follows:
Public IP addresses Private IP addresses
199.203.73.15-199.203.73.115 200.0.0.100-200.0.0.200
The private addresses are translated to public addresses by specifying addresses Translation in
the NAT tab of Localnet’s network properties window. Source addresses for the outbound packets
from hosts in Localnet will be translated to 199.203.73.12 as shown in the figure below.
A.
True
B.
False
Explanation:
As we can see in the exhibit, this statement is wrong because when the packet is coming back
with a reply from Internet to the gateway the source address should be the address of the Internet
server, not the translated public address from the Checkpoint Firewall making the translation.
Incorrect Answers:
A: The exhibit cannot be true because you cannot have a reply with the same IP address in the
source field that you used to make the request when you lived your gateway in your local network.
