You are responsible for the configuration of MegaCorp's Check Point Firewall. You need to allow two NAT rules to match a connection. Is it possible? Give the
BEST answer.
A. No, it is not possible to have more than one NAT rule matching a connection. When the firewall receives a packet belonging to a connection, it compares it against the first rule in the Rule Base, then the second rule, and so on. When it finds a rule that matches, it stops checking and applies that rule.
B. Yes, it is possible to have two NAT rules which match a connection, but only in using Manual NAT (bidirectional NAT).
C. Yes, there are always as many active NAT rules as there are connections.
D. Yes, it is possible to have two NAT rules which match a connection, but only when using Automatic NAT (bidirectional NAT).
