BINAT OK over IPsec on 2.1?

I understand that bidirecting NAT'ing is now supported over IPSec in 2.1?
So, the procedure to solve a routing conflict for this would be:
192.168.1.0/24 <=pfsense 2.1==>=binat==> 192.168.70.0/24 <====ipsec====><=remote endpoint=> 192.168.1.0/24 (NAT'd local LAN)
Configure IPSec tunnel as normal on the pfSense side, but in Phase2 under Local Network NAT/BINAT, select Type: 'LAN subnet' and fill in 192.168.70.0/24?
Then, after the tunnel establishes, the remote LAN can access the local IPs as follows?
192.168.70.1 -> 192.168.1.1
192.168.70.2 -> 192.168.1.2
192.168.70.3 -> 192.168.1.3
Yes, NAT+IPsec works fine on 2.1 and later.
It's close to what you said: Select Type=LAN Subnet, and then in the NAT options directly under that choice, pick Network and then enter 192.168.70.0/24
Firewall rules would still refer to 192.168.1.x (rules after NAT, as always)
