I'm brand new to IPP and I have a client that wants to print directly to our
copy shop's printer. I'm attempting to set this up without breaching
security. I'm aware that I can use VPN tunneling (IPSEC), but I'm exploring
other options.
We have a Linux Firewall running on Redhat. Our internal network is running
a 192.168.4.0 scheme that goes through the firewall to the router.
I have a small Hawking 10/100 Parallel Print Server hooked up to my printer,
which allows IPP printing. It's assigned to 192.168.4.100. I can print
just fine internally. I'm at the point where I need to assign firewall
rules to let this through.
Do I need to forward port 631 to the firewall's external interface through
NAT to allow IPP to go through? Ideally, I'd like to be able to print to
the Firewall's external IP. Is this secure? Is there a better
configuration?
Thanks.
