Qing:

I can confirm that Luiz' patch does work. I applied it and was able 
to disable my workaround. The only thing I would change is that I 
would turn off the "gateway" flag (RTF_GATEWAY) in the routing 
table entry. (You suggested this, implicitly, when you mentioned 
using the -iface flag.) This is because the "tun" interface is 
really a bridge, not a gateway.
