[cups.general] Accessing Printer Behind NAT

[Michael Sweet]

What you'd need to do is add a printer on the "gateway" system using a real printer driver and then share that printer out.

Also, make sure you allow "ipp" access (TCP port 631) through your firewall on the gateway machine...

When I set up a printer definition on the LAN machine pointing to the virtual printer on the firewall, it seems to be work, but then when I try to print, it fails.  The CUPS error file shows an error #0700: server-error-not-accepting-jobs.

I actually got it working once, but then I continued to tinker with things and now can't get the LAN side to print to the WLAN printer.  I have ruled out any firewall issues.
