That is how chilli works with ieee802q option... But, you are trying to tag the wireless interface with a bridge on the local host (eth0.x) ... And that will not work for the reason you showed... That since chilli is working with eth0 (and knows nothing about eth0.x), any reply from chilli will NOT be tagged by eth0.x. If you use a VLAN switch and have chilli handle eth0 (with no eth0.x tricks) then is should work fine...

And eth0 is connected to a port on the managed switch where VLAN tagging is enabled. On the same switch there are many untagged VLAN ports where each client is connected. By doing so, we accomplish "client isolation" - ie the clients are blocked from talking to each other.
