I'm exerimenting with a new network at home with a Astaro Home edition as the heart. For WLAN I have bought a TP-LINK TL-WA901ND. It's a cheap access point so I don't expect mush of it. However it has a few features I like to try out. One of them is that it can handle up to 4 SSID and tie them to VLANs. But, I have not been able to make that work yet.
Before I start blaming the hardware, I want to make sure I have configured everything correctly. Since I have never worked with VLANs before, chances are that I have made a mistake.
My setup is simple: Astaro box have three interfaces, WAN, LAN and WLAN. The WAN is not connected to anything yet and the LAN is Ethernet standard created by the installation wizard (10.0.0.1/24). On the WLAN I have configured three VLANs: Private (VLANID 10, 192.168.10.1/24), Guest (VLANID 20, 192.168.20.1/24) and Open (VLANID 30, 192.168.30.1/24). The physical interface is connected directly to the access point without any switched in between.
The access point is configured to host 3 SSID corresponding to the Astaro setup and tag each with the appropiate VLAN. According the official documentation the access point uses 802.1Q for VLAN.
I have also configured DHCP servers on all VLANs and liberal packet filter rules for testing (VLANs -> Any -> Any).
So far, so good. I can connect to all SSID with corresponding security. But I never get a DHCP lease and if I configure IP manually I can't get traffic to the Astaro box or vice versa.
If I turn of VLAN tagging and configure the WLAN inteface as Ethernet standard, all works as expected.
Here is some things I am wondering about: Is there a problem connecting directly between two divices using VLAN without a VLAN aware switch? Even when I turn on VLAN on the access point it has a non VLAN IP address for management (I have tried to put it one 192.168.0.2 and 192.168.10.2 without any difference), can that interfere with the VLANs? Have I missed anything with my configuration?
