I have a question regarding port forwarding in multiserver setup. Should all ports for http/s, DNS, mysql, etc. be forwarded to the main server ip (192.168.0.xxx), or each port to the corresponding server ip? If the second is right, which port for secondary DNS as 53 will be forwarded to the primary?
The master server only controls the other servers, all traffic should go to the server you are using for it. Nameservers should be spread over separate connections, for redundancy. They should also be spread geographically.
