It’s possible to enable DNS forwarding using BIND and including reverse lookup for the zone. Once you are done with the config of a basic bind server, all you need to do is configure "/etc/bind/named.conf.options and conf.local" with the following options and restart the service.

In this example we have got 2 DNS server's resolving.

SERVER1 = = domain : HM.LOCAL : IP:

SERVER 2 = = domain : DEV.LOCAL :IP:

We need to resolve local requests for "hm.local" on SERVER 1 and forward any "dev.local" domain requests (forward and reverse lookups) to SERVER 2 and hence need to configure SERVER 1  to achieve this.

To start with add the zone dev.local to "/etc/bind/named.conf.local" and add the forward zone to the config file.

This is a easy-to-follow setup and config guide for of Cacti (Source install) on CentOS and Red Hat flavour OS. The setup is straightforward as it does not evolve any source code compiling but instead just a MySQL db setup and configuring users and permissions. The setup requires a user to have Root access to a Linux host.
