Firewall problems?

[Ulli]

On F17, my Transmission cannot get any incoming connections. On F14 it worked. On Windows 7 it works. UPNP is enabled. (I skipped F15 and F16, so no idea about them.)

I just discovered that F17 has a new firewall mechanism, so I'm wondering if it's blocking my connections. system-config-firewall doesn't say anything, but I guess it doesn't really affect the new FW.

Any ideas how I can get Transmission working, or how I can find out if a firewall is active or unlocking ports? The new firewall-applet doesn't seem to do anything, and firewall-config isn't available, nor does a package by that name exist... :blink:

F17 is using Firewalld Linux aint Windows, Windows aint Linux. read the release notes on Firewalld http://fedoraproject.org/wiki/Features/firewalld-default & http://fedoraproject.org/wiki/FirewallD

Well, I never said Linux was Windows or the other way around, only that my router works with UPNP and that I managed to get Transmission working with versions of Linux and Windows, so I'm assuming that the F17 firewall is causing my problems.

I read the release notes of FirewallD (of course), but couldn't quite figure out if or how my system is affected. Some packages weren't even installed (like firewall-applet), the feature page (http://fedoraproject.org/wiki/Features/firewalld-default) suggests that I need to install and start things (so does that mean that by default no firewall is active?) and neither an iptables process nor a firewalld seems to be running.

Is some firewall blockage active in the kernel even without a daemon running? I have no idea, i'm not an expert. If anyone could offer me some informative feedback, maybe without the condescending tone and RTFM, I'd appreciate that.

I'm using F17/Xfce and also tried to understand firewalld but couldn't (I also got the impression that by default it's disabled).
I'm with an active torrent from linuxtracker now in Transmission so it works. Maybe it's something with the torrents you're trying?

I have been mucking about with firewalld, trying to get it to do things. The documentation is lacking, to say the least. If anyone has anything to add or correct below I would be very grateful!

From what I have gathered. . .

You put each network interface in a "zone" and each zone has a list of "services" that it allows.

Defaults are in /usr/lib/firewalld/ as xml files. They are very straight forward and can be copied to create new services or zones, which you can put in /etc/firewalld under the appropriate directory.

*Note that firewalld could not read the xml files in /etc/firewalld if I symbolically linked them there, probably some permission thing; I didn't bother to track it down.


Anyway, the default zone for any interface is defined in /etc/firewalld/firewalld.conf . If you want to put a specific interface in another zone it can be done by editing the appropriate file in /etc/sysconfig/network-scripts/ and adding a ZONE= line.

Services can be added/removed from a zone on the fly with firewall-cmd, but I am not sure if those changes are carried over on a reboot.

I seem to have it up and running well enough, but it certainly isn't as pleasant as using the old style firewall. Hopefully it will pick up steam.

Fedora hosted documentation: https://fedoraproject.org/wiki/FirewallD

Although the "How to Test" section in Features seems to show examples.

I haven't tried F17 yet. I was hoping there would be a plasmoid or applet that will help display information and give the opportunity to change settings. Although, from what I read above, it's not there yet. No firewall-applet & no firewall-config?

there is a firewall applet fir firewalld, but I can't seem to get it to run for me here. :(
