# -
# - [*] At boot, by default no address rewriting is attempted.
# - [**] This code is currently totaly untested.
# -
# - Flags can be combined by adding them. Common settings
# - would be:
# -
# - To enable rewriting in quiet mode:
# - # echo 1 > /proc/sys/net/ipv4/ip_dynaddr
# - To enable rewriting in verbose mode:
# - # echo 3 > /proc/sys/net/ipv4/ip_dynaddr

# - Parameter will be set to "false"

# - packets are routed and destinations.
# -
kernel_dont_accept_redirects=true
# - Activate Reverse Path Filtering (Antispoofing)
# -
# - Reverse Pfadfilterung aktivieren. Dies hilft durch automatisches Ablehnen
# - von Quelladressen, die nicht mit dem Netzwerkinterface übereinstimmen,
# - sicherzustellen, dass Pakete legitime Quelladressen benutzen. Dies hat
# - Sicherheitsvorteile, da es IP Spoofing verhindert. Wir müssen es für
# - alle net/ipv4/conf/* aktivieren, da sonst die Validierung der Quelle
# - nicht voll funktionsfähig ist.
