Danke fuer die Antwort, dem Link nach zufolge liegt es nicht an der MRU/MTU 1500.
Stellt sich die Frage, woran es dann liegt... hier ein weiterer Ausschnitt meiner plog:

Danach connectet er wieder. Hab DHCP aktiviert, jedoch jedem Clienten + dem Server manuell eine IP zugewiesen, weil der DHCP dies nicht tat. Der Server ist auch ueber 9 statische IP's zu erreichen (nicht Netzwerkintern), manuell zugewiesen. Ich weiss nicht inwiefern da was zusammenhaengen kann.
