I have two Sites (Site A) using Fortiddns, and Site B using Daillup . There is VPN tunnel between them and it's working fine. I want to make DNAT for my server and it's behind Site B. I don't have public IP Addresd .

it's not working in this scenario?

If I understand well your case, DNAT should be on site-A, mapping the site-A's public IP address to the server's IP address that is located on site-B.

What is not working? Any logs? Any blocked traffic?

In your VIP, you just need to put 0.0.0.0 as External IP address, and it should work.
