This trap and all different in the LANCOM generated traps are sent to
all manually configured trap receivers, just like to each registered
LANmonitor, which can evaluate this and possibly all other traps.
8.3.6 Strategies for Firewall settings
Firewalls are the interface between networks, and they restrict to a smaller or
larger extent an unhindered data exchange. Thus Firewalls have opposite
objectives than networks, although they are a part of them: networks should
connect workstations, Firewalls should prevent the connection.
