    Hello, has anyone solved the problem of remote printer/copier installation - when connecting via
    SecuExtender is not found device installation program (autodiscover)?
    I can manually add the printer and add IP adress printer.

    I enabled ports on the firewall: according to table 3 here https://www.cups.org/doc/firewalls.html

    So anybody have idea, why AUTODISCOVER search not found device ?

    Thank you

      Hi @kyssling,

      Based on my understanding, most auto-discovery protocols run in broadcast mode, and broadcasts cannot pass through Layer 3 routing.
      They only work within the same subnet.

      Maybe AutoDiscover works only on the same subnet?
