I have most ports closed on my router except the obvious (POP, SMTP, FTP, Interbase, SQL Server, MySQL and VNC). Could I have a port closed that CUPS needs? I have identical problems with Linux (RHE) and Mac Tiger.
Only the LPD server needs port 515 open, for IPP it's port 631. LPD is clear text. IPP can be clear text or SSL. I don't think the Windows Server IPP implementation does SSL though.
