[Openswan Users] Openswan -> Cisco over GRE

Hey All,


I've managed to get the cisco -> openswan ipsec tunnel up and
established. However, I had to use rightsubnet and leftsubnet to
establish the connection. I am using BGP for dynamic routing everywhere
else, so I would prefer to route over a GRE tunnel that is encrypted by
IPsec(again, as I do in openswan to openswan tunnels). 


If I leave the leftsubnet/rightsubnet, when I up the connection ipsec
simply replaces the bgp learned routes with it's own static route,
breaking the routing.


I tried to remove the leftsubnet and rightsubnet, but the cisco device
refuses the connection with "policy not acceptable".


Has anyone managed to get it up and running in this fashion?
