| Posted by userkiller, 10-14-2012, 09:12 PM | | Hello guys, i have i have 5 IP's assign to me.
i have a small network configured but im trying to set up a more modern network for educational purpose.
I have 2 servers both with the same specs hp dl 360 g5 32gb, duo 2.6 quad and 6x72gb sas drive. running Centos 6.3 and solusVM
2 watchguard firewalls, running pfsense 2.1
2 dell powerconnect 2724 switches.
My goal is to have a dedicate mail server inside a vps.
Dedicate DNS server something like Powerdns.
I'm stuck here, can i add a local IP to my PowerDns VPS? and later do a NAT?
Or do i need to assign one of my dedicate IP to ns1 and another one to ns2?
Example powerdns ns1=10.0.1.14 ns2=10.0.1.15 and do a NAT or do i need to use my ip assign to my by the ISP? ns1=97.121.242.x51 ns2=97.121.242.x52
same goes to my Email server

Using the firewall you can easily do either a DNAT or SNAT as needed. This will provide you with more flexibility. For example you could use the same public IP for both Mail and DNS but map them to different internal private IPs (servers) on the firewall.
So back to your question, Yes, you can allocate a local IP to your VPS and do a NAT on the firewall

| Posted by darockProjects, 10-16-2012, 01:47 PM | | Hey,
You can apply the firewall rules to map the public IP (A.B.C.D) to your internal subnet (192.168.1.0/24) as follows
VPS 1 = A.B.C.D:2001 <--> 192.168.1.1:80
VPS 2 = A.B.C.D:2002 <--> 192.168.1.2:80
The idea is that you can do different IP (public and internal) and ports combinations and you can conserve your IP addresses.
