VLAN ID 1 with port 1,3,4,6,7 port 3 is tagged and is dedicated to the firewall and the other ports are untagged with pvid 1
VALN ID 2 with port 3,8 (port 3 is tagged and 8 untagged with vpid 2)
VLAN ID 3 with port 3,5 (port 3 is tagged and 5 untagged with vpid 3)
VLAN ID 10 with port 2 untagged with vpid 10

The 802.1q VLAN scheme looks ok to me, permitting it's implemented as documented...

My problem is that if I connect a laptop on the port 2 (VLAN 10) if I put on it the same class range ip of VLAN 1,2,3 I can ping the other pc on the respective lans.

...this should not be possible, indeed. The VLAN 10 is an isolated VLAN on it's own.

 

Just for curiosity, the notebook does not have WiFi active and the ping does go over the backdoor channel and the router?

Thank you for the answer.

The laptop is not wifi connected and when I unplug the cable on port 2 the ping fail.
