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?
