If by "works locally" you mean i works on the LAN the server is in but
not on another LAN containing the clients that is standard behavior for
cups.

To use cups to serve printers to clients in a different LAN in
the /etc/cups/client.conf file you need to have a line:
ServerName 70.238.70.20

where in this case 70.238.70.20 is the address of the server.
Note: 70.238.70.25 is not address of my cups server.
