VLAN Trunk, Access Ports, Native Vlan

Hi Guys,
Please I am having a problem configuring trunk and access ports and a native/default vlan on my mikrotik RB951Ui-2HnD 6.38.1.
I want to have 2 vlans… vlan20 and vlan30.
Trunk port: ether3 (vlan20 and vlan30)
Access ports: ether4 (vlan20), ether5 (vlan30)

I tried the manual on the mikrotik website: https://wiki.mikrotik.com/wiki/Manual:Interface/VLAN#Port_based_VLAN_tagging_.231_.28Trunk_and_Access_ports.29
https://wiki.mikrotik.com/wiki/Manual:Interface/VLAN#Port_based_VLAN_tagging_.232_.28Trunk_and_Hybrid_ports.29

But it only works for trunk ports. It doesn’t work for access ports and I can’t find a guide for native vlans.
Please help guys. Thanks

Create a bridge for each VLAN ie VLAN 20 bridge and VLAN 30 Bridge. Then add VLAN 20 and ether 4 to VLAN 20 bridge. do the same for vlan 30.

There are also some interesting examples for hardware switch config.

Thanks dgnevans, Sob…finally working.
