Hallo,
seit einiger Zeit sehe ich in den Router-Logs meiner DSL-EasyBox ständig Warnungen vor UDP Loops. Was hat es damit auf sich? Handelt es sich um gezielte Angriffe gegen meinen DSL-Anschluss? Wie kommen die Angreifer an meine IP? DynDNS-Dienste sind nicht vorhanden...
Auszug aus dem Router-Log:
