<div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>Thank you for your help Thierry and Alexander and the others. I am definitely getting a response from the scanner on my network. Below are the steps that I took, following all your suggestions. Airscan-discover and ahavi both find the printer. I think we are close. but scanimage -L still does not work though. Below are my detailed steps. The ahavi command lists alot of ports that are used and I have been only opening up a few, like 80 tcp, 443 tcp, and 8612 udp for sending/recieving, Do I need to modify the firewall for all the ports that ahavi lists?. This computer is a dual boot and although I am in ubuntu linux, the scanner recognizes the Windows computer with the same IP address (when it is on). I thought I would mention that too.</div><div><br></div><div>Thank you again for all your suggestions,</div><div><br></div><div>Anton Khabbaz <br></div><div><br></div><div>I tried your recommendations and here is what I did.</div><div>1. <br></div><div>I modified the output forwarding rules to allow traffic from and to my ubuntu computer (192.168.1.25) to the Canon TS9120 printer (192.168.1.16) , port 80 tcp</div><div>The output of ufw status is listed (other rules and ports like udp 8612 are omitted for clarity)<br>To Action From<br>-- ------ ----<br>192.168.1.25 ALLOW 192.168.1.16 80/tcp <br>192.168.1.25 80/tcp ALLOW 192.168.1.16 80/tcp <br>192.168.1.16 80/tcp ALLOW OUT 192.168.1.25 80/tcp `<br></div><div><br></div><div>2.
