Encapsulation)
Accept
Activate this rule if you are
using GRE-based tunneling
mechanisms in your LAN,
such as the PPTP VPN
gateway incorporated in
Microsoft NT 4.0. This rule is
not necessary if you are only
using the AVM Access
Server’s VPN functions.

Drop
All packets that have not
been accepted or dropped
above this point are treated
as intrusion attempts. These
may be tunneled packets (i.
e. IP-over-IP encapsulated
packets), or routing
protocols, such as OSPF or
EGP packets. These packets
would also be dropped by
the filter profile’s default
action, of course. This rule is
nonetheless included so
that you can activate its log
option if you want to trace an
attack on your firewall.
