Description Carlos Sanchis 2009-01-05 12:59:28 UTC

Althoug 'cups' is an allowed service, remote CUPS queues cannot be browsed.

Comment 1 Carlos Sanchis 2009-01-05 13:00:53 UTC

I've also tried enabling UPD port 631 (sometimes even TCP) but it doesn't help. Disabling the firewall allways solves the problem.

Comment 2 Marcus Meissner 2009-01-05 14:29:21 UTC

correct.

in external mode the firewall does not accept incoming packets (for UDP).

Move the network card to the "Internal" zone if you are in a trusted network.

Comment 3 Carlos Sanchis 2009-01-05 17:20:46 UTC

Sometimes I am in a trusted network, sometimes I'm not. It's a laptop. If I move the card to the internal zone I'm better off disabling the firewall. I should be able to keep the current configuration and still be able to browse remote printers.
