Range port TFTP
Published: May 12, 2023 - 3:28 PM
Hello, I'm following up on my last post about TFTP on WAPT.
For your information, we had indeed opened port 69, so the client was communicating with the server, but the TFTP protocol uses ephemeral UDP ports for the response, and these ports were blocked.
Once the ports were opened, it worked perfectly, however, the network administrator is a bit hesitant to leave the UDP responses open in "any" mode.
Is it possible to fix the TFTP ports somehow?
At the very least, what is the TFTP response range?
For example, on WDS, the ports used are 64001 to 65000.
