Printer Port Forwardiing

This worked. Then I had to factory reset my GL-AXT1800. I set it up the same way, and now I can't see the printer...

My Canon MF656CDW laser printer is hardwired to the GL router into a LAN port. It is assigned a STATIC IP Reservation of 10.1.1.5. I've power cycled the printer and the printer displays 10.1.1.5. And the GL "Client" list shows it is active at 10.1.1.5.

I also set the Port Forwarding to forward port 9100 from my home network to the LAN side of the GL. That worked great, and Printer Discovery on my windows machines found the Canon printer and we could send print jobs to it, like it was on our home network directly. But after I reset the GL and set it up again, now my computers on my home network can't find the printer.

Not sure what changed. Any ideas?

I understand that it worked before. But maybe you can do more port forwarding e.g. port 515 as well. Canon printer has a lot of ports.
