My company wants to establish a VPN link, hosts its own web server, email server and ftp server (Each on a different machine). I'm a little unsure of the required number of registered (static) IP needed & how to set it up.
1. Can I only use ONE registered (static) IP address on a DNS server. This DNS server will then route the message to the other server (ftp, web and email server) using private IP address. See the following:
(Registered IP 1) (Private IP address..................)
2. Or do i need to have a Registered Public IP address for each of my web, email, and ftp server. See the following:
INTERNET-------router ------Web server (Registered IP 1)
------Email server (Registered IP 2)
------ftp server (Registered IP 3)
(Registered IP 4) (Private Address)
3. Or is there a better way to do this?
Pls clarify and thank you very much.
