Description
This is the test case to check if firewalld and NetworkManager are working together.
How to test
1. Connect to a network and check if the network is part of the default zone:
firewall-cmd --list=all --zone=public
The output should look like this ('em1' is in used as an example):
firewall-cmd --list=all --zone=public zone: public interfaces: em1 services: dhcpv6-client, ssh
You can also check the resulting firewall directly:
iptables-save | grep ZONES
The result should be something like this:
:POSTROUTING_ZONES - [0:0] :PREROUTING_ZONES - [0:0] -A PREROUTING -j PREROUTING_ZONES -A POSTROUTING -j POSTROUTING_ZONES :PREROUTING_ZONES - [0:0] -A PREROUTING -j PREROUTING_ZONES :FORWARD_ZONES - [0:0] :INPUT_ZONES - [0:0] -A INPUT -j INPUT_ZONES -A FORWARD -j FORWARD_ZONES -A FORWARD_ZONES -i em1 -j FWDI_ZONE_public -A FORWARD_ZONES -o em1 -j FWDO_ZONE_public -A INPUT_ZONES -i em1 -j IN_ZONE_public
'em1' is the interface used by NetworkManager for the connection. NM will automatically add the interface of a connection to the default zone.
2. Change the zone of a connection.
Add ZONE=work to the ifcfg file of the connection.
As root use an editor and add "ZONE=work" to the end of the ifcfg file of that connection. The result should look like this:
UUID="......................" NM_CONTROLLED="yes" BOOTPROTO="dhcp" DEVICE="em1" ONBOOT=yes HWADDR=......... TYPE=Ethernet DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System em1": ZONE=work
NetworkManager will automatically reconnect and the zone will be set accordingly:
firewall-cmd --list=all --zone=work
The output should look like this:
zone: work interfaces: em1 services: ipp-client, dhcpv6-client, ssh
3. Remove the ZONE from the ifcfg file again and the interface will be placed into the default zone 'public'.
4. Set a new default zone in the firewalld config file as root with an editor:
The result will look like this:
# default zone # The default zone used if an empty zone string is used. # Default: public DefaultZone=home
Reload firewalld:
firewall-cmd --reload
Reinitiate the connection in NetworkManager and check if the conneciton is using the new default zone:
firewall-cmd --list=all --zone=home
You can also set the default zone with 'firewalld-cmd --set-default-zone=zone', but at the moment there is a SELinux problem with this - it forbids firewalld to write in it's own configuration directory. This will be fixed.
