Description

Scenario: OpenVPN: [sense1 client] -> [sense2 server] [sense2 client] -> [sense3 server]

- Servers and clients are bridged to physical port leading to switch.
- When i plug computerA behind sense1 client, and computerB behind sense server3 all works fine.
- When i switch computers with each other, OpenVPN routing table is still pointing to old locations (https://xxx.xxx.xxx.xxx/status_openvpn.php). Means that sense3 server is still pointin computerA to be found behind sense2, and sense2 is pointin it behind sense1

Mac routing table on L2 TAP tunnel SERVER is not refreshing nor timing out (unplugged computer and mac-address still in table after 20hours). Bridge interface mac-table is fine and pointing to right direction on all devices (ifconfig bridge0 addr).

- If it matters, im using qinq's over those tunnels, and hp aruba are connected to sense bridges.
