Help: pxe + tftp Green -> Orange



  • i have the following scenario:

    • GREEN and ORANGE network
    • pxe/tftp server in the ORANGE network
    • clients from the ORANGE network are able to boot from the server without a problem.
    • tftp-proxy activated for GREEN and ORANGE
    • from the logfile i can see the tftp proxy looks like to work

    my problem:
    clients from the GREEN network can't boot from the pxe server in the ORANGE net

    my question:
    can this setup work? are just a few rules missing or does this simply not work without opening the whole firewall?

    another test i made:
    if i try to connect with the windows tftp client

    
    tftp 192.168.100.2 get pxelinux.0
    
    

    i get the following messages in the log:

    Do you have captive portal enabled on one of those networks, by chance?
