I have a question around TFTP inspect. With firewall rule configured to allow connection from outside interface on port 69.
When TFTP inspect is enabled on an ASA firewall, does this specifically only allow for file transfer from client to server ?
Does the above rule also allow for TFTP RRQ from server to client ?
I've tried doing google search with no luck. I will try to get an environment up and running to test this.
In the mean time can someone provide an answer from their experience ?
Protocol inspection examines the bidirectional flow for conformance with the protocol.
Do you mean you are allowing connections from hosts upstream of the outside interface or from the interface itself? Can you share your ACL entry (or entries)?
