I have a linux router (Centos 6) that I built. It has eth3 and wlan0 bridged together as br0. I have not been utilizing vlans up to this point.
I have a wireless AP that is tagged vlan 42 for a guest SSID that I want to isolate from the rest of the network, and I have a Netgear L2 switch that is set up with the vlan info.
On the linux router, it appears I cannot add vlan 42 as a vlan interface on br0.
What is the proper way to do this? At some point, wlan0 can go away and I can just have eth3 for the lan interface on the router, but that isn't until we test the new AP. I don't mind reconfiguring the network stack in the meantime to make this all work.
Updated with network drawing and details on current configs. This is where I am at now. I can ping 10.4.3.1, but traceroutes and pings don't make it any further, and a client on the aerohive guest network cannot ping anywhere, including 10.4.3.1.
I'm fairly sure that I have the switch configured correctly from talking to a tech at Netgear, and same for the Aerohive. Do you see something wrong with anything in my ifcfg files? Or something else that I'm missing? Any other info I can provide you? I really appreciate the effort at helping me here!
