Hello,
Sorry for re-using an old post, but since it is just exactly like my problem I thought it would be more appropiate to ask here.
I have an old DGS-1248T with an old firmware (1.00). Recently I've been trying to setup Tagged VLANs, but like the problem explained before in this post, it seems to tag every traffic in this port (on every VLAN).
I think it should tag every VLAN but the one specified in Port VID Settings, which should leave Untagged, isn't it?
I can't find any information about this and the manual explains there should be somewhere to specify which port to tag/untag on which VLAN. I think this is only for newer versions of this Switch.
All this leads me to another question: Could I update the firmware of my Switch so I can have this functionality?
Thank you very much in advance and sorry for the inconveniences.
