I didn't see a way to create a zone dynamically (e.g., using firewall-cmd). Is this correct? Thanks, Scott

Accessibility to flags and states?

Hello. With firewall-cmd (and/or firewall-config), will it be possible to access the protocol flags and the state of the frames? For example, will it be possible to do the equivalent of the following commands? iptables -A INPUT_TCP -p tcp --syn --dport ssh -m state --state NEW -j ACCEPT or iptables -A CHECK_BAD_TCP -p tcp --tcp-flags ALL SYN,RST,ACK,FIN,URG -j DROP thx

Proper way to change zones?
by Patrick 05 Apr '12

05 Apr '12

Hello! I am trying to make use of firewalld now that I am in F17, but documentation is slim :). I have created a zone xml file in /usr/local/lib/firewalld/zones/ and added some services to /usr/local/lib/firewalld/services/ . I have then linked them to the appropriate folders in /etc/firewalld. Even after reloading firewalld, it does not list my new zone when I issue the command firewall-cmd --get-zones. I have set my interface to use my new zone in the appropriate /etc/sysconfig/network-scripts file. Now when I issue firewall-cmd --get-zone-of-interface=eth0 I get no output, instead of "public," which was the zone it used to receive by default. If I issue "nmcli -f NAME,DEVICES,ZONE con status" it lists my new zone, so I guess that is something :). Am I doing this all wrong?! Thank you for any assistance, Patrick

FirewallD Rule for Port and Interface
by Scott Talbert 04 Apr '12

Hi, I have been looking at firewalld in Fedora 17 in order to understand how to convert an iptables command that I use in a script into a firewalld one. The iptables command that I'm using is: iptables -I INPUT -p udp -i $INTERFACE --dport 67 -j ACCEPT With firewalld-cmd I can do: firewall-cmd --add --port=67/udp But there doesn't seem to be a way for me to specify an interface as well? As in, I only want to open UDP port 67 on a specific network interface, not all interfaces. Thanks, Scott
