Hi, For a machine connected over the internet to pass through a firewall and print using samba what ports do I need open? I am using CUPS and SAMBA so do I need to open up the ports to connect to CUPS as well as SAMBA? Basically is the situation when printing with samba at the point of connection to the printer a or b below? (a) remote machine --> print job --> firewall --> samba server --> printer (b) remote machine --> print job --> firewall --> printer The problem is I can see the samba shares and see the printer but I cannot connect to the printer even though all the Samba ports are open properly.
