LAN and WLAN

[balanga]

If I have LAN, WLAN and WWAN connections to the Internet how do I select (or even find out) which interface is used?

How, for example, would I to compare throughput using speedtest?

If you haven't done anything special (PF's route-to for example) just looking at the routing tables should be enough to figure out where traffic is going out the network.
