That sound more like what I was looking for. Would be nice to do it using Wifi only, but as it seems I will not get around using 2 more wireless devices ( perhaps "hAP lite
which is rather inexpensive)
and use them in a station/client setup in which I have to configure my current routers to treat them as a LAN to LAN setup.
If you want 2 aps with both lans advertised from both aps, then I 100% agree and recommend that you use seperate radios for this than you are using for the router-to-router connection.
Build the router-to-router connection as I explained in my previous post, and then you will want to add a couple of things to let the APs allow "roaming":
On wlan1 on both routers, add two vlan sub-interfaces:
wlan1.lan1 (vlan id 10)
wlan1.lan2 (vlan id 20)
Also create two bridges: brLan1, brLan2.
Now on Router1:
Make sure the LAN1 configurations are all using brLan1 bridge
(you probably already were because of how the 2011 uses 2 internal switches)
Add vlan interface wlan1.lan1 to this bridge.
Add wlan1.lan2 to brLan2 - but don't bother to put any IP address settings or anything - this is just to send wifi traffic back to the other side.
Make sure all LAN2 settings are using brLan2 bridge
add interface wlan1.lan2 to brLan2
add interface wlan1.lan1 to brLan1 and don't put any settings here.
When you add the external APs to your network, configure them to use vlan10 on wlan1 and vlan20 for wlan2, and create ethX.lan1 vlan id 10 / ethX.lan2 vlan id 20 on an ethernet interface and add those to the appropriate bridges, and connect the APs to ethX interface.
I will draw a more detailed diagram of this with vlans and such becase "a picture is work 1000 words."
