In my router (DSR-1000AC with Firmware 3.11_WW), I created a new VLAN 192.168.3.x following the instructions from
HOW to Setup Two VLANS ‑ DSR‑Series.
I used a simple switch (not managed) and I connected it to port 4 of the router. Then, I connected a PC to this switch and it took successfully an IP from the new VLAN, the 192.168.3.2.
Till here all good. However, this PC can't see the devices from the default VLAN 192.168.0.x (e.g. a network disk). The ping doesn't return anything..
The above guide notes that:
InterVLAN Routing can stay “Off” this way there is no way that both networks will see each otherSo I turned in ON that setting. However, the devices from the 2 subnets can't "talk" each other. So my question is how can enable that?
