By design, you can't re-share a shared printer.

I created a virtual printer on the firewall machine using IPP which points to a remote printer on one machine on the WLAN network.  I can print from the firewall machine to the remote printer OK.

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.
