TCP/IP Printing through Firewall with NAT

[Claude Leduc]

Ok yesterday I posted something similar...I tried every tips you gave, but still have the same problem...I'll explain again...My HP UX has a private IP ex:10.10.0.1 behind a firewall using NAT for public access...I print outside the office to a branch office...My public IP address is mapped in my print queue ex:print queue=mtlo1 address=24.200.1.1...When the firewall is activated, no print job leaves the HP UX, but when I deactivate tha access-list, everything goes...I tried the ports 515, 111, 2049, even 7, icmp is enabled...I know my problem is due to blocked returning port, but which one??? --- TIA!
