Stateful inspection for UDP and ICMP protocols

Hi everyone,

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

Best regards.

Stateful inspection for UDP and ICMP protocols

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.
