Exchange Server and Astaro 2.22

cbarone
I am running Astaro on (2) Nic cards and have setup an Exchange 2000 server on a private ip on my local Lan.

External Nic - 216.158.xxx.xxx
Internal Nic - 192.168.1.100
Exchange Server - 192.168.1.203
DNS Server - 192.168.1.200

I want to point my registered domain name to the DNS server on the private LAN so my Exchange server can use a registered domain name. 

Can this be done through DNAT? 

With register.com I have to point the domain name to a dns server name, not an IP.

I know it would be easier if I created a DMZ and put public IP address' on my DNS and Exchange server, but would rather use DNAT if it can be done.

Your help is greatly appreciated!

    Hi Carone,
    DNAT should work. 
     
    Define External IF as 216.158.xxx.xxx
    Define Internal DNS as 192.168.1.200

    Use PRE DNAT as:   
    External IF -> DNS

    Post DNAT as: 
    Internal Server -> DNS

    So requests on the external IF will be forwarded
    to the Internal Server

    You should also setup Packet Filter Rules to allow the needed protocols.  I did something similar with Exchange and allowed POP3 and SMTP
    using DNAT.
