Question:
Which of the following correctly describes the routing table lookups performed by a FortiGate operating in NAT/Route mode, when searching for a suitable gateway?
Options:
A lookup is done only when the first packet coming from the client (SYN) arrives
A lookup is done when the first packet coming from the client (SYN) arrives, and a second one is performed when the first packet coming from the server (SYN/ACK) arrives.
Three lookups are done during the TCP 3-way handshake (SYN, SYN/ACK, ACK).
A lookup is always done each time a packet arrives, from either the server or the client side.
Correct Answer
The Correct Answer for this Question is
A lookup is done when the first packet coming from the client (SYN) arrives, and a second one is performed when the first packet coming from the server (SYN/ACK) arrives.
