Denying a specific subnet
Figure 39 shows an example in which a server attached to network 172.16.1.0 shall not be accessible from outside
networks connected to IP interface lan. To prevent access, an incoming filter rule named Jamming is defined,
which blocks any IP traffic from network 172.16.2.0 and has to be bound to IP interface lan.
