Shorewall and printing problems in the LAN ( loc ) zone
Guys,
Just a quick check. From what i have read in the
shorewall site, intrazone traffic is allowed
completely by shorewall i.e. there is no filtering or
packet size limiting ,etc,etc.
I ask this becos after getting shorewall up and
running well, someone has complained that they cannot
print pdf files larger than 100k at one go but that
they have to print one page at a time.
Some details;
interface - eth1 ( 192.168.2.x)
- printer type - fuji xerox photocopier/printer (
192.168.2.99)
-there is also a squid transparent proxy runnig on the
shorewall machine.
But, printing from a machine in the LAN zone to a
printer in the LAN zone shoud not be affected right?
regards,
marco.

If your two LAN systems are in the same subnet, your shorewall system is probably not even seeing the traffic. If you want to look into it a bit further, throw a shorewall dump into http://rafb.net/paste/ and someone can look at it. -- Paul <http://paulgear.webhop.net> -- Did you know?

Re: Shorewall and printing problems in the LAN ( loc ) zone
But tom, my understanding of traffic within a zone is correct right? shorewall doesn''t do anything to traffic in a zone , between machines/ printers right? i am just a little stubborn because that was what i told the user.... shorewall will not disturb printing as both the computer and the printer are in the same zone. is printing does improe when i do ''shorewall clear'' what setting would i need to do ? --- Tom Eastep <teastep@shorewall.net> wrote:> Paul Gear wrote: > > Linux Advocate wrote: > >> ... > >> But, printing from a machine in the LAN zone to a > >> printer in the LAN zone shoud not be affected > right? > > > > That''s right.
