I have a Linux based wireless access point. It has eth0 interface for ethernet, ath0 for wireless and br-wan as a bridge between the two.
bridge name bridge id STP enabled interfaces
br-wan 8000.001567000041 no eth0
Q: How can I add vlan tagging on the wireless side so that all the outgoing traffic will be tagged, and only incoming tagged traffic will be accepted?
I'v tried creating a new vlan using vconfig
vconfig add ath0 15
ip link set ath0.15 up
I then used a computer with a traffic generator software to send frames through the Ethernet port of the access point. Using tcpdump -e I can see them pass through both ath0 and ath0.15, however no tagging is added whatsoever.
