Sorry, my fault. I didn’t see http://forum.mikrotik.com/t/css610-8g-2s-in-vlan-behaviour/144150/1 the main topic in the other threads are other than VLAN setup.
I’ve been tinkering with the VLAN setup this morning and I’ve got unsatisfactory results. I can’t make it run. On the other hand I rescued and upgraded to the latest firmware an old RB260GS and my net runs fine. Thus, I guess that there is something wrong with the CSS610 firmware. If somebody makes some progress, please let us know.
Thanks.
