Hi i have this setup, and id like to have some clues or config examples of DNS:
Id like to install bind9 in an ubuntu 18.04 in address 192.168.2.2 ( dmz, orange zone),
This dns would have entries from green zone.
pc1,class5.com 192.168.0.5 ( green)
pc2,class5,com 192.168.0.6 ( green)
professor.class5,cin 192.168.50 ( reserved ip in dhcp server)
servidor.dns 192.168.2.2 ( dns server in dmz, orange)
Also would like to know how to add a dynamic ip from blue zone
192.168.4.5 ( ip in blue, wan obtained dynamically)
I suppose i need only one dns to all this no ?
