Is Fastpath bi-directional?

[ryan14]

If I create a rule that Fastpath's for example:

Szone: INSIDE

Dzone: OUTSIDE

S: ANY

D: 1.1.1.1

Does return traffic from 1.1.1.1 to what initiates the connection get Fastpathed or do you need another rule to Fastpath the reverse traffic? Is that true for UDP traffic?

FTD, like an ASA, acts as a stateful firewall. So the return traffic for an existing allowed connection (fastpath or otherwise) is automatically allowed.
