Been having problems with LPR printing through our firewall.
LPR will only use source ports 721-731 but on the firewall I keep seeing 721 and 722 being used and the firewall dropping these connections with "Attack info: TCP flags do not make sense"
We keep restarting the print queue and after a while the jobs start going through and we see the source ports looping through 721-731.
It seems to fail every few days for an hour or so at a time.
