I have a bit of a special configuration, my Univention cluster runs on a bunch of VPSes exposed to the public internet. I would like to make Samba / LDAP only listen on a VPN interface though. I have been able to establish the tunnel and connect to the other servers in the cluster perfectly, but the only issue I have run into is the fact that the default IP of each server(set in UCR) keeps getting added to the DNS record (in the UCS internal DNS server) for the server’s hostname.
For example, I set the Host Record for
172.16.0.1 (internal VPN IP). However, after a few minutes, I see the external IP of the server hosting
dc1 getting added to that record. How do I prevent this from happening?
