Auto serve printers to remote subnets as to local subnet.

Please help.
Have posted at Apple, Cups.org and here. Anyone doing this?
Looking for help to share printers to multiple subnets.

Network – 3 small private subnets connected by point to point T1s, no firewalls or other traffic limiting between subnets:
192.168.1.*
192.168.2.*
192.168.3.*

Server – 1 10.4.2 G5 DP 2.3 server controlling most aspects of service including print qeue hosting via cups
located at 192.168.1.2
The server does know how to route traffic to the other subnets.
For testing purposes the firewall on the server is wide open to all traffic in above subnets.

Clients – at least 2 10.4.2 clients on each subnet – all bound to server above(LDAP) which provides many settings for Preferences as set in WGM.

Issue to be resolved:

Clients on same subnet as server obtain “shared” printers (queues set up on server and shared via IPP) directly from the server. Clients on the other subents cannot obtain “shared” printers automatically. These printers show up automatically under “shared printers” in the print dialog box without any need for further setup. I would like the other subnets to be able to get the printers from the server directly as well.

I assumed that editing the cupsd.conf of the client machines and adding that clents should poll the server’s IP address would allow the clients to obtain the “shared” printers for use. The server’s log indicates a “Forbidden” request has been made by the client requesting the printers.

As a non UNIX user I’m not sure where I have gone wrong with the setup. I can get a VPN client (10.4.1) which is issued an IP on the same subnet as the server to get the “shared printers” in the manner described above but not the clients on the different subnets. I assume that I am missing some bit of setup on the cups server in the server machine….

I have tried changing the cupsd.conf server config to remove permissions on printer usage…but on restarting the service my changes are removed and replaced with what looks like limiting to local subnet only.

Anyone have any suggestions. Thanks for your time in advance.
