I am having a world of problems here and can't see what is going wrong!
Use the Draytek to connect to the internet and provide WLAN access. Single port to connect to the GS724T and tag VLANs. Configure ports to belong to a particular VLAN, devices on a VLAN can communicate with each other and the Draytek only. If device is connected to a port belonging to VLAN2 the router provides an IP from LAN2 Optional: Each SSID to be on a different subnet to isolate traffic.
The failed setup:
I have set up VLANs on the Draytek using the same IDs that I used on the Netgear. I think it is best if I post screenshots of the relevant sections so you can see what I have tried.
On the Port PVID Configuration page I tried changing ports 2-6 so the configured PVID was set to 20 but this resulted in no network access as I had a 169.x.x.x IP. If I manaually set my IP it still had no network access. The same result is seen if I uncheck any port from the general VLAN (VID 1).
I don't mind all IPs on the same subnet as long as devices can't communicate with devices in another VLAN. I would like devices connecting to the router wirelessly to have access to wired devices which are part of the same VLAN i.e. printing from an iPad to a networked printer.
Help would be much appreciated, I am sure I am missing something simple!
