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:

[41951.119486] filter_IN_public_REJECT: IN=wlp0s20f0u3 OUT= MAC= SRC=192.168.1.1 DST=224.0.0.1 LEN=36 TOS=0x00 PREC=0x00 TTL=1 ID=10725 DF PROTO=2 MARK=0x3214

It sounds like 224.0.0.1 is related to mdns broadcasts, so it seems firewall is also still blocking these (despite mdns being allowed service).

Am I specifying these in the wrong place? (Per Connections - System Settings, my wifi is in Firewall zone “home”).
