NAT issue behind Ipsec IP for local network

[scorpoin]

Hello,

Here is the simple diagram to get the basic picture of scenario

I've 3 interface on my Pfsense firewall

LAN: 172.16.190.0/24
WAN : 1.2.3.4
Ipsec : 192.168.3.2/32

I've created IPsec successfully and I can ping site-B ipsec ip 192.168.3.1 from my firewall.

Site-B allowed traffic from only 192.168.3.2 and I dont have controll on that firewall/site . Now I want to NAT my lan traffic via ipsec tunnel ,so my I can access 192.168.3.1 from my lan network .I'm lost how do I get it done .

Regards

Any one have any idea?

Does site-B need to allow my internal subnet as well to make it work ?

I'm trying to edit this post as solved , but failed to edit keep getting popup message you can edit post from 36000 hrs .

Any way I use NAT/BINAT option again in phase-2 of ipsec.

Local : 172.16.190.0/24
NAT-BINAT : 192.168.3.2/32
remote : 192.168.3.0/30

that's all and reconnect the ipsec tunnel and every thing worked like a charm . I didnt add any firewall extra rule any where .

Regards
