Thanks. Do we also need to specify the 10. addresses in the encryption
domain?

Thanks again.

You need to specify the NATed address, since NAT happens before  
encryption for outgoing packets.  This makes sense if you think about  
it, since you can't NAT something that's been encrypted.

Good luck!
