Reading about Mageia Linux. I don't run it so take what I say with a grain of salt. I would Look into uninstalling Shorewall Firewall in Mageia (The web says Mageia uses Shorewall Firewall)
Just use Mageias package manager to uninstall it. If wanting to go into

A note about config files
The default configuration directory is located at /etc/shorewall/.
Shorewall global configuration file is located at /etc/shorewall/shorewall.conf. This file sets options that apply to Shorewall as a whole.
The /etc/shorewall/zones file declares your network zones. Rules about what traffic to allow and what traffic to deny are expressed in terms of zones.
The /etc/shorewall/interfaces file serves to define the firewall's network interfaces to Shorewall.
The /etc/shorewall/policy file defines the high-level policy for connections between zones defined in /etc/shorewall/zones.
To provide exceptions to policies, add rules to /etc/shorewall/rules. Use this file to open or close ports and so on.
To blacklist IPs, applications, MAC address, and subnets use the /etc/shorewall/blacklist file.

Like I said. I don't run rpm based distros or Shorewall Firewall. So this is the best I can suggest as a quick fix.
