could someone with more knowledge of the tun device please take a look 
at the code around line 387 in net/if_tun.c? It looks like tunoutput() 
drops all packets here that aren't of the AF_INET family - most notably, 
it drops IPv6 packets.

We hacked around this with the simple fix below, but I'm not sure if 
there are any drawbacks...
