suse 11.2, firewall must be down for wireless printer

English Network/Internet
#1

basically I have a home wireless network and running openSuse 11.2 and using Yast … hp j6480 wireless (setup with hplip) printer (multifunction fax/scan/printer), toshiba laptop wireless, and netgear wireless router … as long as the firewall is not running I can print just fine … as soon as I start the firewall I have connection errors … I have noticed the wlan0 and eth0 are configured in the external zone for the firewall so I added “cups” in the Firewall Configuration: Allowed Services … the Firewall configuration: Summary displays

=======================================
Firewall Starting

UDP Ports: ipp (631)
Broadcast Ports: ipp (631)

================================

also in the hplip forum it mentioned that hplip uses ports 161, 162 1and 9100 …

now being a confused noob … am I missing something very simple?

I’m a bit confused. Are you saying you need to bring down the openSUSE firewall to print to the HP J6480? If so, that does not make sense to me.

I have an HP Photosmart Premium c309a wireless printer, and all I did was add cups support to the openSUSE firewall. I can print to that printer with no problem from an openSUSE-11.2 PC on the same LAN (and even those openSUSE-11.2 PCs on a subLAN).

There are settings in the openSUSE firewall for “mDNS/Bonjour Support for HPLIP” and “ZeroConf/Bonjour Multicast DNS” but I’ve never needed those. Adding cups support to the openSUSE Firewall (under YaST) did the trick for me for printing.

Scanning is more difficult re: the firewall.

Previously I had 11.0 and everything worked fine (print,scan,and fax) … then I installed a larger harddrive to the laptop and installed only 11.2 it started having problems … but yes I have to stop the firewall for it to connect to the printer … so any direction you can lead me to try?

Well I tried the mDNS/Support for HPLIP, it loaded and everything just worked right away …

Consider this SOLVED and thanks for your help
