We have several servers running Cups, Fedora Core2/3, and printing to
various printers on a variety of Netgear printservers, 3com print servers,
and Savin copiers. All of these are printed to via their LPD interface and
are RAW queues.  All of the Netgears recently stopped working if we are
running Shorewall > 2.0. The Policy and Rules in Shorewall allow ALL from
LOC to FW and vice versa. Shutting off shorewall immeadiately allows both
web access to the print servers and printing access. (In fact queued up Jobs
start spitting out) We have 1 site with Shorewall 1.4 (which is about to go
EOL) where the Netgear still works. No other print servers seem affected.
Anybody seem anything like this? 

TIA,

Chris Smith
