IPPSEC Tunnel Phase 2 NAT doesn't work
I've created a new IPSEC Tunnel
Phase 1 is connected without no problems, NAT-T is set to auto
phase 2 is using NAT/BINAT translation to a single IP address,
I can see that phase 2 is connected in the IPSEC status page.
Side B is seeing the traffic i'm generating, the issue is that side B is seeing my private local network IP address instead of the NAT/BINAT translation address, although it is configured to translate in the phase 2 config.
For some reason PFSense is not applying NAT on this specific tunnel (other tunnels NAT is working as expected)
I also tried with several different IP addresses in the NAT.
What could be the reason for NAT/BINAT translation not to be applied?
How can I further troubleshoot this issue?

It seems that AES-256 doesn't translate NAT/BINAT with DH-Group 2
I changed the DH-Group to 14 and the issue solved.
