So I've got the TP-Link T1600G-28PS up and running with 4 VLANs and the connected devices are routing and working great except for Internet Access.
I'm setting it up at home initially for testing and connecting to my HG659b VDSL router. I naively thought I could connect an untagged port from the T1600 to a LAN port on the HG659 and be able to route to it. i.e.
However it doesn't appear to work that way. Devices on the other Vlans cannot ping the HG659b LAN interface (but they can ping other devices on Vlan2). A device on Vlan2 can ping the HG659 but cannot use it as a route to the internet despite having a static route in place.
Do I need the HG659 to be in Bridge mode? I was about to try but there is no way to specify a PPPoE connection in the T1600.
Am I missing something?
