Added some info to the post. Firewall is blocking 3289 UDP from my printer, so I added 3289 UDP to open ports for “home”, “public”, and “internal” zones. However, I’m still seeing filter_IN_public_REJECT entries in dmesg, so it seems the firewall is still blocking these. Is there a different way I should be telling it to allow requests on this port?
Firewall also allows mdns service (again, in “home”, “public”, and “internal” zones), but I also see entries like this:
Added “mdns” service to allowed list for public zone, still get the SANE error. (Previously added 5353 UDP per another suggestion – sounds like this is the port for mDNS)
Our neighborhood has the Magical Chicken Wing bush. The dog thoroughly inspected it for months afterwards, and still checks on it now and then just in case.
