I have a problem currently with printing through a PIX firewall. The traffic is outbound through a PIX 525 and is a TCP connection on destination port 9100.
Packet capture has shown the TCP handshake to be SYN, SYN ACK, ACK then PSH ACK, and I cannot get the print to work.
I google'd "printing 9100 PIX" and found a couple of relevant results which point to the PIX dropping this type of traffic as a security risk.
Is this the case, and if so, as it is very legitimate traffic, what can be done to solve it ?
Any ideas please?
