Hi,

my setup is the following:


Site A:

Lan: 192.168.100.0/24

Lan_IP: 192.168.100.1

Transfer: 10.2.81.0/24

Transfer_IP: 10.2.81.1


Site B:

Lan: 10.2.82.0/24

Lan_IP: 19.2.82.1


I'm doing a site-to-site IPsec wich is working. I can ping from both routers 
(pfsense, juniper) to each other (10.2.81.1 <-> 10.2.82.1) but not from the 
clients in my LAN (192.168.68.x <-> 10.2.82.x). I'm now trying to setup a 
Transfer-Net with NAT / BINAT routing:


Site B should reach the clients on site A via an 10.2.81.x ip-address and not 
via an 192.168.100.x ip-address. So i want to map 10.2.81.0/24 <-> 
192.168.100.0/24.


First i tried to do this via the NAT/BINAT setting inside the IPsec settings:


Site A IPsec Phase2


Local Network: 192.168.100.0/24

NAT/BINAT translation: 10.2.81.0/24

Remote Network: 10.2.82.0/24


That didn't work and i tried the same thing with 1:1 NAT from the Firewall tab:


Site A


External subnet IP 10.2.81.0

Internal IP: 192.168.100.0/24

Destiantion: 10.2.82.0/24



No matter which mapping i choose, if i try to ping from 192.168.100.x to 
10.2.82.x, pfsense routes the request through the WAN interface instead of the 
IPsec / Transfer-Net Interface. How can i tell pfsense to route the traffic 
from my Lan through the IPsec tunnel (not WAN) and do the NAT?


Thanks
