Hello, I have two computers (that are involved in this problem), phoenix is my Gentoo workstation and desktop-1 is someone else's Windows box. Someone else happens to have a printer and I don't, so, from time to time I use his printer. The printer is shared, obviously, thru SMB (it's a windows box). I configured CUPS to connect to it (I just used the KDE Kcontrol to configure it). My problem is that when I bring up my firewall (a firewall using iptables on phoenix, just protecting phoenix) printing stops working. In fact, all access to desxtop-1 thru smb stops working. The firewall is very simple, a simple stateful all-incomming-closed firewall: # iptables -vL Chain INPUT (policy DROP 35510 packets, 16M bytes) pkts bytes target prot opt in out source destination 329K 558M ACCEPT all -- lo any anywhere anywhere 36M 54G ACCEPT all -- any any anywhere anywhere state RELATED,ESTABLISHED 3 228 ACCEPT icmp -- any any anywhere anywhere icmp echo-request limit: avg 30/min burst 5 120 7057 ACCEPT icmp -- any any anywhere anywhere 1 60 ACCEPT tcp -- any any anywhere anywhere tcp dpt:ssh Chain FORWARD (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 21M packets, 3426M bytes) pkts bytes target prot opt in out source destination phoenix ~ # Do you know why after bringing up this firewall I can't use the printer anymore and/or how to solve it ?
