Just bridging between a wifi interface in client mode (connected to an 
AP as a client) and another interface (nothing tinc related, the 
same goes for ethernet) does not work.

An accesspoint accepts only packets from mac addresses that have 
registered with it before (association+authentication).

Possible workarounds are things like mac-address-spoofing/replacing or 
proxy-arp, but thats a not so trivial setup.
