Hi,
I'm currently trying to share my printer using cups.
Setup:
Router 1:
internal: 192.168.178.1/24
external: ADSL dynamic
Client:
connected to router 1, IP 192.168.178.22/24
Kubuntu 6.10
Router 2:
WAN connected to router 1, Wan-IP 192.168.178.2/24
Lan-IP 192.168.1.1/24
Server connected to router 2, IP 192.168.1.2/24
Kubunu 7.04
Routing configured on router 1 and 2, ping client--> server an server-->client
works.
However I'm unable to see the shared printer on the client. Is there sth
special to configure in cupsd.conf to get it working across different
subnets? while client+server were on the same subnet it worked great.
greetings
Jang

Jang,
I'm not a CUPS guru, but I was a networker at one point. This sounds to
me like a networking issue, not a CUPS configuration issue. Since CUPS
uses some sort of a discovery protocol, the client is probably sending a
discovery broadcast message to 255.255.255.255. Since you are talking
about 2 routers with WAN connections, then there is also a good chance
there there are firewalls running. It would not be uncommon for a
router with a firewall to block all broadcast messages by default.
Check on router two to see if it is blocking broadcasts. If nothing
else, then specifically put in an allow statement for 255.255.255.255 on
umm.. google, google, google UDP port 631. Hopefully that should fix
things.
