I'm wondering how one would create a network in order to be able to assign public IP addresses on servers??
Excuse the bad wording and phrasing but I haven't done anything like this before since I've just graduated from the CCNA but have been asked to design a small data center infrastructure.
My idea is that I will use a Cisco 1801 coupled with a 2950T switch to provide NAT based access to servers.
The issue I am having however is that I would like to create 2 public DNS servers and assign public IP's to each of them. Doing this server side is easy my issue however is, how do I configure the 1800??
It will be used as primary gateway so no probs there with a simple stub network design, however is it possible to exclude some of the internal switch ports from the NAT? Of course the 1800 has a L2 managed switch but where there is a managed switch it means there are VLANs and I'm sure that the IOS will complain if the IP address of the routable port is within the same subnet as on of the VLAN's.
Is it possible for anyone to give me any hints or clues as to what and how to manage the design of this?
I mean DMz styled access would still just create a 1:1 NAT relationship with all ports being opened up but the machines still having private IP addresses.
Most likely I would need a L3 switch but haven't got the budget for that.
Many thanks for any responses!
