VLAN configuration issue.

Hello all,
I have a problem with VLAN configuration on my new MikroTik router.

main idea:

  • have VLAN 20 on ports erher2-ether7 as untagged


  • have the rest of the VLANs tagged on ports erher3-ether7


  • have vlan1 untagged on port ether8 (it works)


  • have all vlan tagged on port ether2 and sfp-sfpplus1 (maybe vlan1 untagged, but not necessary)

The Internet works fine for ether8

Now 2 raspberry pi connected to port ether2 and port ether3
Both hosts have no DHCP IP received.
