ich habe da auf dem Jessie-Aufbau ein Problem mit der Verbindung von Kiste1 zu Kiste3.
Auf Kiste3 soll die apt-Paketversorung, den Aufbau habe ich so vorgefunden.
Auf Kiste1 und Kiste3 sind IP-Table aus.
Konstellation:
[Kiste1 eth0 10.1.2.2] ----- [Kiste2 eth1: 10.1.2.1, eth0: 10.1.1.3] ------- [Kiste3 eth1: 10.1.1.1]
Ping
10.1.2.2 --> 10.1.2.1 OK
10.1.2.2 --> 10.1.1.3 OK
10.1.2.2 --> 10.1.1.1 100% loss
10.1.2.1 --> 10.1.1.3 100% loss
Ping innerhalb Kiste2
Code: Alles auswählen
$ Kiste2: ping -I eth1 10.1.1.3 10.1.1.1
PING 10.1.1.1 (10.1.1.1) from 10.1.2.1 eth1: 56(124) bytes of data.
