Dear Colleagues,
I have been treying to set up VLANs on my OPNSense machine (v. 20.1.6) and 3 x TL-SG108E switches, but so far I managed to get the VLANs working on first switch only, but not on second and third.
Each VLAN has been set up on IGB1 interface and has its DHCP server running.
Please see the link with description and setup of my network:

Could you please advise where lies the problem?
Thank you in advance.
Best regards,
Maciej.
Maybe untag all ports from default VLAN on switch B and C?
