Tftp server behind a PfSense firewall



  • Hello,

    we have a problem accessing our TFTP server from the internet, it says all the time that port 69 does not responds to the outside…
    The scenario is as follows, there is no nat in the scenario we are running only official ip addresses:

    TFTP SERVER ---> PfSense Firewall ----> ISP provider

    and the access list allows "source" ANY and the "destination" is the ip address of our TFTP server.

    Tried to open both 69 TCP and UDP...

    We have opened the port 80 on the same way for the web server which is also running on the same windows server as TFTP server,
    but TFTP does not work at all while it`s ok with web server port 80.

    so remember we are trying to reach our TFTP server from the Internet, so PfSense needs to route the traffic to the internal network...

    Any idea why its not working when we opens a TFTP server port ?? the TFTP server us up and running and responding on the "localhost" 127.0.0.1 on the server where its installed...

    I hope that someone can help me with this issue...
    Is there anything we have to enable or install on the PfSense in order to get it working ? if Yes what and how ?

    Thank You

    Try using the TFTP proxy under System > Advanced on the Firewall/NAT tab. TFTP does not play well with NAT.
