Simple VLAN without VLAN-aware router and DHCP aka Port-based VLAN

I did manage to get the tagged VLANs (802.1Q) working with DHCP, mutiple switches AND VLAN-aware router - the whole shebang. However, I tried to poke around with the simple setup with not vlan-aware ...

    Thanx a lot for the time and effort. Looks like, I'm ending up as that guy I mentioned before, who got it working...somehow :O

    Actually, I tried all kinds of combinations and...eneded up with exactly the same setup I began with...and this time it was working! With DHCP and everyting!
    So the approach the Asymmetric VLAN is very simple:

    E.g. 

    - define VLAN 10 + 20

    - define the trunk/gateway - VLAN50 (or keep the default VLAN1)

    - make ports 2+3 only members of VLAN10 and VLAN 20 respectively

    - make all ports needing access to the outside network (extra switch of router) members of VLAN50

    - set port 1 to PVID50

    - set port 2+3 to PVID10 and PVID20 respectively

     

    And the setup works as intended  - port 2+3 are online, but cannot talk to each other as they are on different VLANs.

    Now, the biggest question still remains - Why the #¤%# didn't it work before ???!!!!!

    A few reboots were made, yes, but otherwise, nothing else!

    Additional question:

     - What exactly are Tagged VLANs needed for then comparing the Untagged if the asymmetric VLANs support the network segmentation and DHCP ?
