Strange connection issue TL-SG108E behind AVM 6600 CableBox
Hi,
i have a strange issue with my TL-SG108E behind my cable box (AVM 6600).
Connection is like this:
Cable --> AVM 6600 --> TL-SG108E --> NAS, Satelite Receiver, etc.
Cable Box is the gateway (192.168.0.1), TL-SG108E was set to 192.168.0.2.
I can access the internet from all devices without problem, all devices behind TL-SG108E can communicate with each other but i cannot access any device behind TL-SG108E from my Cable box!
In the meanwhile i tried upgrading the firmware and did a factory reset. Now the switch works as DHCP client at 192.168.0.47.
When i connect my NAS directly to the cable box i have no problem, but then it is not visible for any device behind the TL-SG108E.
So it seems like TL-SG108E separated the networks here. I did not setup any VLAN.
Also i understand that after a reset, the switch should behave like an unmanaged switch.
Any ideas?
Thanks for your help in advance!
Alex.
