Well it is recursive. You need to already have a route to 192.168.3.1/32 
  for tunnel to come up. If you already have the route and you STILL 
want to tunnel, you need a more specific route for 192.168.3.1/32 that 
DOESNT use the tunnel, so that the tunnel doesnt try to establish itself 
over itself, which would do bad things to the router if it actually kept 
trying to do that.

I dont know if local policy routing for gre or ipsec works properly yet. 
Didnt last time I checked 12.4
