Thanks for the response!

I wasn't sure if it was goign to be possible, but thats pretty awesome using NAT over IPsec with OSPF.

One question as the documentation isn't fully clear on. Do I have to have a tunnel subnet equal to the network I need to tranverse the tunnel? in this case /24 or can I still have just a point to point subnet /30 for my tunnel?
