# Clean up kernel modules on exit
# If set to yes or true the firewall related kernel modules will be

# Default: no

# Lockdown
# If set to enabled, firewall changes with the D-Bus interface will be limited

# IPv6_rpfilter
# Performs a reverse path filter test on a packet for IPv6. If a reply to the
# packet would be sent via the same interface that the packet arrived on, the

# /proc/sys/net/netfilter/nf_conntrack_helper will be changed.

# AllowZoneDrifting
# Older versions of firewalld had undocumented behavior known as "zone
# drifting". This allowed packets to ingress multiple zones - this is a
# violation of zone based firewalls. However, some users rely on this behavior
# to have a "catch-all" zone, e.g. the default zone. You can enable this if you
# desire such behavior. It's disabled by default for security reasons. Note: If
# "yes" packets will only drift from source based zones to interface based
# zones (including the default zone). Packets never drift from interface based
# zones to other interfaces based zones (including the default zone). Valid
# values; "yes", "no".
# Defaults to "no".
