Hi,

I have this setup for my ER605:

Port 1: WAN

Port 2: VLAN2

Port 3: Open

Port 4,5: VLAN1

Port 1 is connected to the modem in passthrough mode.

Port 2 is directly connected to a PC acting as a server, running ubuntu.

Port 3 was open, and now connected to OC200.

Port 4 -> Unmanaged Switch -> Managed Switch -> Wireless AP

Port 5 -> Wireless AP

Everything was working fine and Port 1 was isolated through VLAN to the rest of the ports.

After connecting the OC200 to port3, I tried setting up the VLANs the way I had set up earlier.

But I am not able to get the ip address on my server PC anymore.

This is what I did:

Settings -> Wired Network -> LAN -> Create New Lan

In The Profile:

PS: I tried with setting Untagged Network and Tagged Network setting to various permutations, but no dice)

Then I go to my ER605 and enable the PVID to 11

It was working all fine before adding OC200. Not sure what else I need to do.
