Hello, I'd like to realise a WLan bridge. I have two small OpenWRT Router. They should talk to each other via Wlan. Also schould they route VLAN's via WLan. I thing it's Easy but not for me. Please see my concept below. How and where can I config the WLan, to work like I want it?
There are IP conflicts on big router. Lan2 and Wlan must be bridged, otherwise use different address and vlan.
If you want to bridge the 2 routers, then on the small router you'll also need to resolve the IP conflicts, e.g Lan1 will be 10.10.12.2
Also keep in mind that one lan host on router small might get an IP from dhcp on router big.
VLANs over WLAN are not standards compliant, you'll need to check whether it's supported by your devices/drivers. Also, as mentioned by trendy, you should only have one DHCP server per VLAN.
Hi that's correct. LAN2 and WLAN schould combinate in one Interfase (bridge) because they have the same rights.
You are right the small router should get the *.2 -IP. Copy and paste Error.
I also thought about DHCP and just VLAN 123 will get one. It would be ok If the Small router send an DHCP IP to LAN2.
As @trendy said, VLAN tags can't be sent directly over wifi. Either use three separate AP instances, or add another layer to the link such as BATMAN. VLANs can be added simply to BATMAN with the notation bat0.N, so it's a potential solution even if you don't use the primary feature of multipoint meshing.
When things are bridged together, the DHCP server can't tell which router / AP a client is connected to. It works like an Ethernet switch, passing packets through without changing their addresses or contents.
It though I Use 2 SSID's. One for Router to Router communikation and one for Router to device like it ist already used for Normal an guest WLAN? Is there a better methode?
You'd use three AP-WDS instances on the same radio, one for lan1 one for lan2 and one for wan. These would have different SSIDs so that on the other side your three client instances connect to the proper one.
