Wireless printing not working with nftables [solved]

[d76]

I followed Hallvor's well-written 'how-to' on nftables

Code: Select all

viewtopic.php?p=736536#p736536 

and it worked well except for printing. When I load the nftables.conf file (either the workstation configuration or Hallvor's customized configuration) I lose the connection with my wireless printer. It would seem I'm missing something rather obvious since I cannot find many others experiencing the same problem.

I've tried opening ports 53 and 443 (taken from the CUPS manual) but that made no difference. I also tried the nftables workstation configuration on the gentoo site

Code: Select all

https://wiki.gentoo.org/wiki/Nftables/Examples

but still no connection.

If I want to print I can either connect the printer using a usb cable or turn off the firewall.

Any suggestions on what I'm missing or where I should look for a solution?

Try turning off the firewall and type (as root)

Code: Select all

# netstat -natp

That should show your printer's port.

Thanks for the quick reply, Hallvor, the information is what I needed.

Once I added the printer port to the firewall it worked as expected. Thanks for your assistance.

I am glad it helped.
