Hi again,
now I spent a few hours trying a lot of things, also inspired by this thread:
But unfortunately I didn't get the expected results.
Two further questions arised:
1. I don't understand "inet" vs. "ethernet-switching" when it comes to filters and VLANs. What path should I try?
2. I don't understand "VLAN" vs. "VLAN interface" and where is the right place to apply firewall filters
I didn't mention that our internet gateway is located in another VLAN than our "Internet only" VLAN. Referring the thread mentioned above things are getting trickier thus, doesn't it?
Thanks a lot for your patience and your support and many greets
Stephan
