11. Firewalls
-------------
Certain tests cut temporarily network connections by defining firewall rules.
Normally even in case of failure these connections are restored. To be sure
that no firewall rules prevent tests from running the flag
net_clear_iptables_in_prepare_phase is set to 1 in default-net.conf.
This flag leads to deletion of *all* iptable chains on the test hosts.
If you do not want this behaviour set net_clear_iptables_in_prepare_phase=0.
