SSL VPN DNS LEAK

What do you mean by leaking? Do you mean there is split DNS mode used if you use the Sophos / OpenVPN client?

Yes correctly.

VPN remote access is config to do full tunneling.

Site to site vpn act the same way

Is your DNS-Server in the Same Subnet, as your Computer is?

Yes, 

The UTM is full workring as DNS.

The image below explain the situation. As you see when browse the internet from site B i get the ip from site a as aspected but the DNS is not forwarding.

In my case is it both, so ssl sts and ssl vpn.

Case1: when ssl remote access to site A i get the public ip of site A and the DNS of site B. I want both to be from site A. 

Case2: when ssl sts from site A to site B the same thing happend.

I just used a random dns leak test site to check this. In both cases the dns is going trhough the DNS from site B, but i want all traffice to travel trhough site B.

I hoop you can help

It's not clear what you're showing us, so we can't suggest an answer.  perfect-privacy.com's test doesn't seem reliable to me.  It has no idea what public name servers we're using.  In any case, if you're setup is as suggested in DNS best practice, you should have no leaks.

i edit the post plz check

What D.N.S query and result indicates that your site B's D.N.S is incorrect?

For example, are you getting an external IP for a site A resource, instead of an internal I.P.?
