Created attachment 1098940 [details] Network dump of scan failure Description of problem: sane-backends-drivers-scanners pings the LAN with broadcast UDP packets port 3289 to look for EPSON scanners, then a TCP connection to port 1865 is initiated. Replies cannot get through because there is no rule in firewalld that can allow the incoming reply to discovery. I believe that writing a rule for such pattern is problematic, as it is not just as "opening" a port. Probably a conntrack helper is needed. The impact of this issue is that scanning with epson does not work out of the box, unlike other OSes. Version-Release number of selected component (if applicable): firewalld 0.3.14.2, sane-backends-drivers-scanners 1.0.25 How reproducible: Always Steps to Reproduce: 1. Open wireshark, attach an epson scanner, filter for LAN traffic && (icmp || udp.port == 3289 || tcp.port == 1865) 2. Execute scanimage -L Actual results: scanimage -L fails with timeout Expected results: scanimage -L prints scanner info. Additional info: disabling firewalld fixes the issue.
