Virtualmin behind NAT, prevent private IP publishing in BIND etc

Virtualmin
1

Hi,
I’m running virtualmin behind NAT and it works just fine. What bothers me is that since it’s behind NAT both the public and private IP are published.

If i check a domain on the host with intodns.com it looks like:

For web01.domain.se the parent reported: [‘194.218.xxx.xxx’] and your nameservers reported: [‘194.218.xxx.xxx’, ‘10.15.19.22’]

Private IP shows up in SPF records and such as well.

How can I prevent the private IP from being published like this?

Thanks.
