Dedicated Server Web/DNS Configuration

Good evening,

I have a Dedicated Server in a data center and i want configure the serve as DNS SERVER (BIND) and WEB SERVER (WHM/cPanel).

1) Is there a security problems when using a DNS SERVER/WEB SERVER in one physical server ? problems when open ports maybe!

2) Is REALLY important to tell the data center to RDNS of NS1,NS2,DNS1,DNS2 and wait 48h before starting configuring the server ?

Thank

Solution
    1. If you have both services on one machine the load/traffic is higher. You have the same secuity issues in both cases (single machine/multible machines).
      You can't run two services on the same port but regularly you run services on their default ports so you shouldn't get into trouble there (HTTP port 80, DNS port 53).
    2. It's not important, BUT: If you have email domains on that server, you need to have a PTR (aka RDNS) dns record set up to point to that machine (from the MX records) otherwise some mail clients/servers may reject or mark your mails as spam/junk.
