[Olsr-dev] Problems with SmartGateway

[Teco Boot]

I have problems with SmartGateway. Add route to tunnel is rejected.

I use dyn_gw also. But this node has no default route. So I think it is not dyn_gw.

If selected GW is a 1-hop away destination, is traffic sent through tunnel? 
Or directly via if wan0? Looks smart. Or is this routing entry unexpected?

Result when SmartGateway should use tunnel.
I moved router #169 from #166 towards #173.
Routing switched to #173, including traffic 
to Internet.
