Stateful inspection for UDP and ICMP protocols

[B. BELHADJ]

Hi everyone,

Can you tell me how the ASA uses stateful inspection for UDP and ICMP protocols?

Best regards.

Basically each time an ASA receives a new connection being UDP it will record the source IP, source port, destination IP and destination port. That information will be holded into the stateful table of the ASA and a reply for that packet will be expected for a specific amount of time (timeout).

That´s it.
