I have a new Epson WF3540 printer/scanner that's on my LAN.
Printing works. I downloaded the free version of VueScan
in order to use the scanner but I can't get it to see
the scanner through the firewall. If I do
systemctl stop firewalld.service
then VueScan sees and controls the scanner. I wrote
the author of VueScan and he said:
You need to configure the firewall so it lets
VueScan communicate with the scanner through
the firewall. It's using mDNS UDP packets.
In the iptables -L output I see several lines that look like
ACCEPT udp -- anywhere 224.0.0.251 udp
dpt:mdns ctstate NEW
Not sure what to do next. I'm not too familiar with
firewall rules. I'm running Fedora 18.
