For the past few weeks I’ve have been trying to solve this, with no luck.
I have a HP MFP and use Vuescan as the scanner software, Vuescan uses the Bonjour protocol to search for devices.
The HP MFP sits on the Blue Network (convenience of location), and can talk to everything using Vuescan on that network fine, but nothing using Vuescan on Green can see it. It does how ever work fine as a printer, and the webportal can be accessed from Green.
mdns-repeater -f blue0 green0
I can see the data being repeated form green0 to blue0, but there is nothing coming back.
In the firewall log is shows;
DROP_Wirelessinput blue0 UDP (IP Addresses) 5353
It would look like there is a Firewall rule, or option, that is blocking the reply, however even if I disable all firewall rules, it still does not connect, with data being dropped.
Is there a way to see or trace what rule is causing these packets to get dropped?
Or can someone point me at what I may be missing.
