Reverse mapping with Dynamic DNS
« on: February 10, 2016, 01:02:39 pm »
Hi there,

Versions
Code: [Select]
Linux srv-net 3.19.0-49-generic #55~14.04.1-Ubuntu SMP Fri Jan 22 11:24:31 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Function and situation
The server is running inside a VMware vSphere cluster [VM Version 8] and is in production. It has 3 network interfaces: internal, external and management. It is NOT working as a gateway/firewall - its purpose is just DHCP and DNS on the internal interface (10.30.1.250). The internal subnet is 10.30.0.0/16 and the DHCP is configured on this interface. Dynamic DNS is activated for sub.tld.com.

Problem description
Forward resolution works without any problem - but reverse not. For some reason the DHCP server can't update the reverse map.

In /var/lib/bind I can't find a reverse zone file except db.1.30.10. Any ideas?
