+# Change default netfilter configuration. When using --netfilter option without
+# a file argument, the default filter is hardcoded (see man 1 firejail). This
+# configuration entry allows the user to change the default by specifying
+# a file containing the filter configuration. The filter file format is the
+# format of  iptables-save  and iptable-restore commands. Example:
+# netfilter-default /etc/iptables.iptables.rules

 # Enable or disable seccomp support, default enabled.
 # seccomp yes
